Abstract:
Nonlinear vibration damage of pipes conveying fluid is a major problem in today’s production and life. Enormous economic loses and safety hazards were caused by nonlinear vibration. Pipes conveying fluid with various branches are very common in actual engineering. Their mechanical properties and vibration mechanism is quite different from that of pipes conveying fluid without branches. This paper showed the nonlinear vibration mechanism of pipes conveying fluid with vertical branches and nonlinear vibration damage factors. Nonlinear vibration theory was used to check the pipeline and some reference data for the rational selection of working parameters were provided.

Abstract:
Both functionally graded materials (FGMs) and fluid-conveying pipes have wide applications in engineering communities. In this paper, the transverse vibration and stability of multi-span viscoelastic FGM pipes conveying fluid are investigated. Volume fraction laws including power law, sigmoid law and exponential law are introduced to describe the variations of material properties in FGM pipes. A hybrid method which combines reverberation-ray matrix method and wave propagation method is developed to calculate the natural frequencies, and the results determined by present method are compared with the existing results in literature. Then, a comparative study is performed to investigate the effects of fluid velocity, volume fraction laws and internal damping on transverse vibration and stability of the FGM pipes conveying fluid. The results demonstrate that the present method has high precision in dynamic analysis of multi-span pipes conveying fluid. It is also found that natural frequencies of FGM pipes can be adjusted by devising the volume fractions laws. This particular feature can be tailored to fulfill the special applications in engineering.

Abstract:
This paper deals with the dynamics and stability of simply supported pipes conveying fluid, where the fluid has a small harmonic component of flow velocity superposed on a constant mean value. The perturbation techniques and the method of averaging are used to convert the nonautonomous system into an autonomous one and determine the stability boundaries. Post-bifurcation analysis is performed for the parametric points in the resonant regions where the axial force, which is induced by the transverse motion of the pipe due to the fixed-span ends and contributes nonlinearities to the equations of motion, is included. For the undamped system, linear analysis is inconclusive about stability and there does not exist nontrivial solution in the resonant regions. For the damped system, it is found that the original stable system remains stable when the pulsating frequency increases cross the stability boundary and becomes unstable when the pulsating frequency decreases cross the stability boundary.

Abstract:
Lateral vibration equations of fluid-conveying pipes system are high order partial differential equations, and the analytic solution is difficult to obtain, so in this paper the numerical solution is obtained by the finite element method. Firstly, the finite element equations of lateral vibration of fluid-conveying pipes were set up, and four kinds of boundary constraints were proposed. The modal analysis of vibration system was carried out by using mode decomposition method, and the system responses were solved by using Newmark method. The impact of pipe span, flow rate, fluid pressure, flow rate disturbance and fluid pressure disturbance on the modes and responses of vibration system were studied. The research results provided theoretical support for the vibration reduction research of fluid-conveying pipes.

Abstract:
Dynamic behavior of axially functionally graded (FG) pipes conveying fluid was investigated numerically by using the generalized integral transform technique (GITT). The transverse vibration equation was integral transformed into a coupled system of second-order differential equations in the temporal variable. The Mathematica’s built-in function, NDSolve, was employed to numerically solve the resulting transformed ODE system. Excellent convergence of the proposed eigenfunction expansions was demonstrated for calculating the transverse displacement at various points of axially FG pipes conveying fluid. The proposed approach was verified by comparing the obtained results with the available solutions reported in the literature. Moreover, parametric studies were performed to analyze the effects of Young’s modulus variation, material distribution, and flow velocity on the dynamic behavior of axially FG pipes conveying fluid.

Abstract:
The dynamic response characteristic of the pipe conveying fluid was researched with the fluid pressure pulsation in this article. For some hydraulic power pipe system, formed the mathematic models and the transfer matrices of the main hydraulic elements based on the fluid network algorithm, deduced the calculation formulae of input-output pressure pulsation, gained the transitive relationship of the fluid flow pulsation and pressure pulsation, and then studied the pressure pulsation amplitude of the hydraulic power pipes with different working pressures. This study, which analyzed the dynamic response of the pipe conveying fluid and discussed the feasibility of increasing the working pressure, is valuable for the design and the application of the pipes conveying fluid.

Abstract:
This thesis studies the linear and nonlinear dynamics of pipes conveying fluid. It consists of four peer-reviewed journal papers, three published and one submitted for publication. The aim is to investigate aspects of the dynamical behaviour of extensible and inextensible pipes conveying fluid, both theoretically and experimentally.In particular, (i) the three-dimensional nonlinear dynamics of a pipe conveying fluid, constrained by an array of four springs attached at a point along its length is examined from the theoretical and experimental perspectives; (ii) the three-dimensional dynamical behaviour of a fluid-conveying cantilevered pipe fitted with an end-mass and additional intra-span spring support is investigated, both theoretically and experimentally; (iii) the nonlinear planar dynamics of a cantilevered extensible pipe conveying fluid is investigated theoretically via two different numerical techniques; (iv) the phase-shift along the length of the measuring pipe of a Coriolis mass-flowmeter is developed (and thus mass-flow rate is determined) analytically by means of a perturbation technique and confirmed numerically. In the theoretical analyses, the Galerkin method and Lagrange equations for systems containing non-material volumes are employed to obtain a set of nonlinear second-order ordinary differential equations. These equations are solved by means of Houbolt's finite difference scheme, the pseudo-arclength continuation technique, and direct time integration via a modified Rosenbrock technique. The method of multiple timescales, an approximate analytical technique, is also used to predict the phase-shift along the length of the measuring pipe of a Coriolis mass-flowmeter.A series of experiments were conducted with silicone rubber pipes conveying water, and thereby the theoretical models have been broadly validated.
Cette thèse traite de la dynamique linéaire et non linéaire de tuyaux parcourus par un fluide. Composée de quatre articles scientifiques ayant fait l'objet d'un examen critique, trois publiés dans des revues techniques et un soumis pour publication, l'objectif étant d'étudier certains aspects du comportement dynamique des conduits extensibles et inextensibles transportant du fluide, de manière théorique et expérimentale.En particulier, (i) la dynamique tridimensionnelle non linéaire d'un tuyau de transport de fluide, contraint par un réseau de quatre ressorts attachés entre les deux bouts est examinée d'un point de vue théorique ainsi qu'expérimental; (ii) le comportement dynamique tridimensionnel d'un tuyau aux extrémités encastrées-libres avec une masse additionnelle au bout libre et un support flexible (ressort) supplémentaire, est également étudié; (iii) la dynamique non linéaire plane d'un tuyau extensible encastre-libre transportant du fluide est étudiée théoriquement par deux méthodes numériques différentes; (iv) le calcul du déphasage sur la longueur du conduit de mesure d'un débitmètre à effet Coriolis (et donc, du débit massique) est mis au point analytiquement au moyen d'une technique de perturbation et est confirmé numériquement. Lors des analyses théoriques, la méthode de Galerkin et les équations de Lagrange pour les systèmes contenant des volumes vides sont utilisés pour obtenir un ensemble d'équations différentielles ordinaires non-linéaires du second ordre. Ces équations sont résolues grâce à un schéma de différences finies de Houbolt, la technique de continuation à pseudo-longueur d'arc, et l'intégration temporelle directe par l'intermédiaire d'une technique de Rosenbrock modifiée. La méthode des délais multiples (dite "multiple scale method"), une technique analytique approximative, est également utilisée pour prédire le déphasage le long du tuyau de mesure d'un débitmètre à effet Coriolis.Une série d'expériences ont été réalisées à l'aide de tuyaux en silicone transportant de l'eau afin de pouvoir vérifier de manière concluante la validité des modèles théoriques.

Abstract:
Structures conveying mass lose stability once the mass exceeds a certain critical velocity. The type of instability observed depends on the nature of the supports that the structure has. If the structure (beam or pipe) is cantilevered (thereby deeming it a nonconservative system), “garden-hose-like” flutter instability is observed once a critical velocity is exceeded. When studying the flutter instability of a cantilevered pipe (including shear deformation) by strictly a linear theory, it has been demonstrated through numerical integration that the values of the critical velocity are only valid for small values of the mass ratio (mass of the fluid divided by the total mass) (approximately 0.1 β< ). This fact is also true if shear deformation is neglected. Also, linear theory predicts the pipe to oscillate unboundedly as time progresses, which is physically impossible. Therefore, shortly after the pipe goes unstable, the linear theory is no longer applicable. If non-linear terms are taken into account from the beginning, it can be shown that the pipe oscillates into a limit cycle.

Abstract:
This thesis undertakes the investigation of the dynamics of two different cases of a slender, flexible pipe conveying fluid: (i) an aspirating cantilevered pipe, ingesting fluid at its free end and transporting it towards the clamped end, and (ii) a pipe conveying a fluid whose density varies axially along the length of the pipe. The general context of the research is first provided by broadly introducing the field of Fluid-Structure Interactions (FSI) and reviewing the basic theory regarding pipes conveying fluid. Subsequently, a numerical approach coupling Computational Fluid Dynamics (CFD) and Computational Structural Mechanics (CSM) to simulate each system is developed in ANSYS™. Lastly, the linear equation of motion is derived for each system and solved using a Galerkin approach; the numerical experiments are then combined with these analytical results to determine the stability characteristics of each system. The problem of an aspirating cantilevered pipe is of both fundamental and practical interest, with applications, for example, in deep sea ocean mining. The motivation for a continued study of the system is demonstrated through a review of previous research on the topic – spanning many years and yielding often contradictory results. The newly proposed analytical model, derived using a Newtonian approach and heavily influenced by CFD analysis, is different from previous ones, most notably because of the inclusion of a two-part fluid depressurization at the intake. In this case, the combined numerical and analytical approaches suggest a first-mode loss of stability by flutter – albeit a very weak one – at comparable but usually lower flow velocities than the discharging cantilever. In the case of a pipe conveying variable density fluid, the analytical model is derived using a Hamiltonian approach, for (i) a pipe clamped at both ends and (ii) a cantilevered pipe. It is shown that these systems lose stability by buckling and flutter respectively, simi
Cette thèse entreprend l'étude de la dynamique de deux types de tuyaux flexibles parcourus par un fluide : (i) un tuyau encastré-libre aspirant le fluide du côté libre et l'amenant vers le côté encastré, et (ii) un tuyau transportant un fluide dont la densité varie axialement au long du tuyau. Le contexte général de cette recherche est d'abord présenté en introduisant le domaine des Interactions fluide-structure (FSI) et en révisant la théorie de base des tuyaux transportant un fluide. Par la suite, une approche numérique couplant la simulation des fluides (CFD) et des structures mécaniques (CSM) est développée dans ANSYS™. Dernièrement, une équation de mouvement linéaire est dérivée pour chaque système et analysée par une méthode Galerkin; les résultats numériques sont enfin combinés avec ces résultats analytiques pour déterminer les caractéristiques de stabilité de chaque système. Le tuyau encastré-libre aspirant est d'un intérêt fondamental et aussi pratique, possédant des applications, entre autres, dans l'industrie minière sous-marine. La raison d'une étude poursuivie est démontrée par un retour sur la recherche antérieure traitant du sujet – s'étendant sur plusieurs années et produisant souvent des résultats contradictoires. Le nouveau model analytique, dérivé utilisant une approche Newtonienne et largement influencé par une analyse CFD, se distingue de ses prédécesseurs notamment par l'inclusion d'une dépressurisation en deux parties à l'entrée. Pour ce cas, les approches numérique et analytique suggèrent tous les deux une perte de stabilité par flottement dans le premier mode – quoiqu'une instabilité très faible – à des vitesses comparables, mais généralement moindre que le cas déchargeant. Dans le cas d'un tuyau transportant un fluide de densité variable, le modèle analytique est dérivé à l'aide d'une approche Hamiltonienne, pour des tuyaux (i) encastré-encastré et (ii) encastr

Abstract:
The study of dynamics of pipes conveying fluid has been the subject of research for many decades now, and various formulations, solution methodologies and applications have been developed. The topic is well understood but research in this area is ongoing as the study of the subject is far from trivial. This is a classical model problem in the study of dynamics and stability of structures mainly because it is a physically simple system capable of displaying a wide array of interesting behaviour in both the linear and nonlinear regime. In this thesis, a geometrically exact fully implicit version of the 3D beam element, which employs the Rodrigues formula for the update of large rotations is used in the solution of the equations of motion. The nonlinear model for the flexible beam conveying fluid has been formulated and implemented to recover the interesting dynamic behaviour of the system in 3D. The advantage of this approach stems mainly from the fact that approach to engineering problems depends upon the intended application, cost from a computational perspective, among other factors which may be taken into consideration, and this provides an alternative to existing approaches. Benchmark problems are presented in 2D and 3D, and confirm robustness and accuracy of the formulation.

Abstract:
Abstract This study deals with optimal design of cantilevered fluid-conveying pipes. The aim is to maximize the critical flow speed of the fluid by means of additional masses, supporting springs or dampers along the length of the pipe. The optimization problem was formulated by modelling the pipe by FEM, using Euler-Bernoulli beam elements. The locations of the additional masses, springs and dampers and the properties of these elements (mass, spring constant and damping constant) were chosen as design parameters. The maximization problem for the critical fluid flow speed was solved by the sequential quadratic programming (SQP) technique. In addition to the presentation of the optimal values obtained for the design parameters, some aspects of the sensitiveness of the systems to variations in these parameters and the robustness of the optimum designs with respect to the stability of the system are studied. Although a considerable increase in the critical flow velocity of the fluid can be achieved in the example cases studied here, a marked sensitivity of the system to the location and properties of the additional elements in the optimum designs was observed. Also, the margin with respect to stability seems to be relatively small in some of the optimum designs considered. Non-linear numerical analysis confirmed the findings of the linear analysis with respect to the sensitivity of the optimum designs to the properties of the additional elements and revealed a very rich post-critical dynamic behaviour in the optimized structures.

Abstract:
This thesis examines the planar dynamics of flexible pipes conveying fluid. The nonlinear equations of motion are derived for cantilevered pipes and for simply-supported pipes, using Hamilton's principle and the force balance method. The resulting equations are compared with previous derivations.
The linearized system is first studied, to get the critical parameters corresponding to the stability boundaries, i.e. the local bifurcations. Then, the nonlinear equations are investigated, both analytically and numerically. Centre manifold, normal form and bifurcation theories are used to obtain complete bifurcation sets which provide the qualitative dynamics of the system. It is shown that chaotic motions may arise under perturbation, or when the motions are constrained by motion-limiting restraints, through calculations of the Lyapunov exponents and the construction of phase portraits, bifurcation diagrams and power spectra. This modeling is in close agreement with experimental observations.

The purpose of this study is to investigate the dynamic characteristics and optimal design of pipes conveying fluid. Finite element method is applied to establish the equations of motions of both the uniform and the tapered fluid-conveying pipes. The established models are verified by using the results reported in the literature. To fully understand the system dynamic characteristics, root loci of the system are plotted to investigate the system stability properties. Sequential quadratic programming (SQP) is applied for the optimal design of pipes conveying fluid. This study shows that although root loci can be used to examine the modal stability properties, the modal vector information must be utilized to determine which mode is unstable when modes get to come across each other as the flow speed varies. For optimal design, it is demonstrated that significant improvement can be achieved for both the cases of minimization of pipe weight given a fixed critical flow speed and maximization of critical flow speed given a fixed pipe weight. The analysis is thus proved to be beneficial to engineering design and economical considerations.

The purpose of this study is to analyze the optimal attachment positions for pipes conveying fluid. The finite element model is established and then simulated under the conditions of different fluid-beam mass ratios. By adding various attachments on different positions of the cantilever pipes conveying fluid, the optimal values and positions of the attachments can be obtained for achieving the highest critical flow velocity. The attachments used in this study are dampers and springs. The goal is to establish the critical flow velocity trend chart of the single attachment condition and to search the optimal parameters effectively by using the genetic algorithm. Furthermore, optimal design for the two-attachment case is also analyzed in this work. The analysis results reveal the optimal attachment positions vary with different mass ratios. As the fluid mass becomes larger, the best condition changes from the single-damper case (β=0.1 to 0.5) to the single-spring case (β=0.6 to 0.9). The critical flow velocity of the two-damper case is higher than that of the single-damper case. Similarly, the use of two-spring performs better than the use of single-spring. The two-damper case with β=0.1 to 0.6 is found to have the best performance. The use of one damper and one spring performs better for β=0.7 to 0.8. The two-damper case yields essentially identical results with those of the two-spring case at β=0.9. As compared with the incremental method for the analysis of one attachment case, the genetic algorithm is far superior in terms of computational time. For the case of multiple attachments, it is impractical to use the incremental method, whereas the genetic algorithm is still applicable and possess superior performance.

Abstract:
The partial differential equations for curved pipes with fluid structure interaction, including the effects of fluid pressure and Coriolis force, Centrifugal force and migration force caused by flow velocity, etc., were derived. These equations were then solved numerically utilizing the transfer matrix method (TMM) in the frequency domain because of its computational efficiency. The results were compared with those predicted by the finite element method and a discrete model. It is demonstrated that the TMM has high precision in the vibration analysis of fluid-filled curved pipes. Furthermore, the influence laws of geometrical properties on the natural frequencies and frequency responses of pipeline are discussed, which show that the natural frequencies of the fluid do not change with the varying of curvature angle when curved pipe filled with steam. But the resonance frequencies of the out-of-plane vibration and vibration amplitudes of the fluid pressure waves are strongly influenced by the variation of curvature angle.

The model divides the pipe into a number of segments from the crack sections and assembles all segments each by each by a rotational spring which has no mass. The stiffness of the spring is obtained through linear fracture mechanics. In order to obtain the modal functions which satisfy the boundary conditions and geometrical discontinuity conditions at the crack’s location, a simple approach is used. That is adding polynomial functions to the modal functions of the uncracked beam. The equations of motion for the cracked cantilevered pipe conveying fluid is derived based on the extended Lagrange equations for systems containing non-material volumes. Not only the virtual work done by the discharged fluid, but also that done by the fluid at the crack position due to the geometrical discontinuity conditions are considered in the present equations of motion. In this article, several numerical examples are given. The comparisons of solutions of the present equations with that of model in existence show that the present work is better. The influences of the relative depth, the position ratio of the cracks, the flow velocity on the eigenvalues are depicted.

Abstract:
Abstract In this paper two nice examples are investigated where a ‘chain’ of n = (1, 2) pieces of rigid pipes contains incompressible and frictionless flowing fluid. We give an overview about the linear and nonlinear analysis of the autonomous system, i.e. when the pipes contain steady flow. Assuming pulsatile flow, the system becomes time-periodic. The stability charts of the linearized system are generated applying a numerical method based on Chebyshev polynomials. Finally, we analyze the effect of the nonlinear part in some critical points of the obtained stability charts and the dynamic behaviour of the original nonlinear periodic system is simulated numerically. The results are shown in Poincaré maps and bifurcation diagrams.

Abstract:
This paper for the first time investigates the nonlinear planar dynamics of a cantilevered extensible pipe conveying fluid; the centreline of the pipe is considered to be extensible resulting in coupled longitudinal and transverse equations of motion; specifically, the kinetic and potential energies are obtained in terms of longitudinal and transverse displacements and then the extended version of the Lagrange equations for systems containing non-material volumes is employed to derive the equations of motion. Direct time integration along with the pseudo-arclength continuation method are employed to solve the discretized equations of motion. Bifurcation diagrams of the system are constructed as the flow velocity is increased as the bifurcation parameter. As opposed to the case of an inextensible pipe, an extensible pipe elongates in the axial direction as the flow velocity is increased from zero. At the critical flow velocity, the stability of the system is lost via a supercritical Hopf bifurcation, emerging from the trivial solution for the transverse displacement and non-trivial solution for the longitudinal displacement and leading to a flutter.

Abstract:
Throughout the oil industry, vertical pipes are used to convey crude oil either offshore from the bottom of the sea or onshore from the depths under the soil. These pipes, otherwise called risers, are attached to a platform at one end and buried under the sea bed or in the ground at the other end. The stability of these pipes is the subject of this investigation. The history of such analysis dates back over five decades when the vibration and stability of fluid conveying Trans-Arabian pipeline network was first studied; albeit for an on-shore environment. For that case, it was found that instability of the flow can be induced by vibration and that if such a horizontal conveyance pipe is supported at both ends, it bows out and buckles when the flow velocity of the conveyed fluid exceeds a critical value. Because of the industrial relevance of such conveyance networks, the problem has continued to generate interest over the years and especially now that deep waters offshore exploration is assuming increased importance in the Oil and Gas sector. When dealing with the stability of these pipes, most workers usually assume the Euler-Bernoulli hypothesis, which requires that plane sections perpendicular to the axis of the beam remain plane and perpendicular both before and after deformation. This essentially means that the deformation of such sections is neglected. However, the Timoshenko hypothesis accounts for such deformation by including transverse shear which is usually neglected. In this paper, the energy method is invoked to derive the governing equations including the effects of external temperature variation along the length of the pre-stressed and pressurized pipe. The stability of such pipes under plug flow model is thereafter presented.

Abstract:
Previous work on stability of fluid-conveying cantilever pipes assumed a uniform velocity profile for the conveyed fluid. In real fluid flows, the presence of viscosity leads to a sheared region near the wall. Earlier studies correctly note that viscous forces drop out of the system’s dynamics since the force of fluid shear on the wall is precisely balanced by pressure drop in the conveyed fluid. The effect of shear has therefore not been ignored in these studies. However, a uniform velocity profile assumes that the sheared region is infinitely thin. Prior analysis was extended to account for a fully developed non-uniform profile such as would be encountered in real fluid flows. A modified equation of motion was derived to account for the reduced momentum carried by the sheared fluid. Numerical analysis was carried out to determine a number of velocity profiles over the Reynolds number range of interest and a simple set of curve fits was used when finer discretization was required. Stability analysis of a pipe conveying fluid with these profiles was performed, and the results were compared to a uniform profile. The mass ratio, β, is the ratio of the fluid mass to the total system mass. At β = 0.2, the non-uniform case becomes unstable at a critical velocity, ucr, that is 5.4% lower than the uniform case. The critical frequency, fcr, is 0.36% higher than the uniform case. A more sensitive region exists near β = 0.32. There, the nonuniform velocity ucr is 23% lower than the uniform case and the non-uniform critical frequency fcr is 49% of the uniform case.

Abstract:
In this paper we obtain asymptotic approximations for the moment Lyapunov exponent, g(p), and the Lyapunov exponent,λ, for a two-degree-of-freedom gyroscopic system close to a double zero resonance and subjected to small damping and noisy disturbances. Using a perturbation approach, we show analytically that the moment and the top Lyapunov exponent grow in proportion to ε1/3 when the damping and noise respectively are of O(ε) and O(ε). These results, pertaining to pth moment stability and almost-sure stability of the trivial solution, are applied to study the stochastic stability of a pipe conveying pulsating fluid.

Abstract:
Internal fluid flow parameters in conjunction with elastomechanical properties of conveyance systems have significantly modulated flow induced vibrations in pipeline and riser systems. Recent advances on the mechanics of sandwich elastic systems as effective vibration and noise reduction mechanisms have simulated the possibility of replacing traditional steel pipes with sandwich pipes in deepwater environment. The dynamic behaviour and stability of sandwich elastic pipes conveying a non-Newtonian fluid are investigated in this paper. For this problem, a set of generalised non-linear equations governing the vibration of sandwich pipes held together in pressurised environment and conveying a non-Newtonian fluid is presented. By linearizing the governing partial differential equation matching the problem physics, under slight perturbation of the internal fluid velocity and other flow variables closed form analytical results for the system dual natural frequencies and stability under external excitation are computed for field designs and applications. Results show that for a given length of pipe, beyond the critical velocity, instability increases with the velocity of conveyance.
