Abstract:
The flow around a circular cylinder has awaken the attention of different researchers since the historic Strouhal's work of 1878. Ever since, many experimental and numeric works have been carried out in order to determine the relationship between the vortex shedding frequency and the flow regime. Recently, a number of studies have been developed using several small modifications in circular cylinder. In this work a circular cylinder modified with a longitudinal concave notch, has been tested in order to determine the relationship between the non-dimensional vortex shedding frequency (Strouhal number) and the Reynolds number has been determined to Reynolds up to 600. Additionally a modified circular cylinder with a longitudinal slit also has been tested in order to determine the Strouhal-Reynolds relationship in several attack angle configurations. The experiments have been carried out in a vertical low turbulence hydrodynamic tunnel with 146x146x500 mm of test section operating in continuous mode. Flow visualization by direct liquid dye injection has been utilized in order to produce vortex images. These images have been captured in still chemical photography for different Reynolds numbers. A hot-film probe has been adequately positioned in the vortex wake to determine the vortex shedding frequency and consequently the Strouhal number.

Abstract:
In order to understand the aspect of the mutual interference flow from two circular cylinders, the visual observation experiment and the pressure measurement experiment were performed by use a water flow apparatus. Two circular cylinders with a diameter of D=10mm were used, and they have been arranged at staggered or tandem. The flow velocity was U=0.25m/s (Re=UD/í, í is kinematic viscosity of fluid). The dye oozing streak method was used in the visualization experiment. In the pressure measurement experiment, the pressure on the surface of a circular cylinder was detected by the single tube manometer, and measurement was performed by image processing using a computer. As a result, distribution of the circular cylinder surface pressure coefficient CP corresponding to the flow pattern and it in each circular cylinder arrangement was obtained. The drag coefficient CD was calculated from the pressure coefficient CP, and change of the resistance in each arrangement was found.

Abstract:
Vegetation association plays important role in the shallower coastal zone for sediment control and the nutrient and carbon absorption. It is necessary to understand the fluid motion including turbulence in the vegetation so that we may evaluate precisely shallow water region including vegetation and wet land. As the first step of research on fluid motion in the vegetation, circular cylinders are sometimes used. Many researches on the fluid force acting on the circular cylinder and fluid motion around the cylinder have been achieved so far. However, the properties of turbulent flow induced around circular cylinders in a wave, especially turbulence transition mechanism and spatial-temporal distribution of turbulence, are not almost investigated. The purpose of this study is to understand the fluid flow including turbulent induced by wave transmitting vegetation association. In this study fluid motion was measured by oscillating circular cylinder arrays in a tank by using the PTV technique.

Abstract:
The flow characteristics around four circular cylinders in equispaced arrangement located near a plane wall were investigated experimentally. The pressure distributions on the each cylinder surface and on the plane wall were measured for a spacing ratio L/D= 1.5 (L, center to center spacing between cylinders; D, diameter) and G/D= 0.2 (G, gap spacing between cylinder surface and the plane wall) in a uniform flow at a Reynolds Number of 5.3 x 104. The 2D U-RANS numerical simulation with k-ω SST as viscous model was used to visualize the flow phenomena occured around the cylinders. The results showed that the flow tend to be biased on the upper side of cylinders configuration. It causes the stagnation at the upstream cylinders occured at lower side of cylinders and results a formation of a narrower wake behind the third cylinder and a wider wake behind the fourth cylinder.Keywords: equispaced arrangement, circular cylinders, plane wall

Abstract:
Viscous flow around circular cylinders is a classical research topic in fluid dynamics with a vast amount of practical applications in the field of offshore marine technology. In the flow around cylinders of finite length, complex wake behaviours and coherent structures occur even at relatively low Reynolds numbers. An understanding of the nature and dynamics behind such behaviour could form a basis for improved designs and innovative solutions for offshore and subsea constructions.In the present study, flow around long finite cylinders at Re = 100 is investigated numerically using the incompressible Navier-Stokes Equations solver MGLET. To study the isolated flow near the free end, a cylinder with aspect ratio L/D = 50 is chosen. The flow over the free end gives rise to a wake consisting of two vortex shedding cells with different shedding frequencies; one small near the free end and one larger in the central region of the span. It is found that each vortex shed in the end cell bends horizontally and connects with the upstream vortex shed from the opposite side of the cylinder. The horizontal vortex shedding is found to give rise to a pair of trailing vortices in the time averaged flow.When a vortex is shed with a large phase difference between the two cells, the vortex is split and connects with other surrounding vortices. This phenomena is commonly referred to as vortex dislocations and occurs with the beat frequency, i.e. the difference between the two vortex shedding frequencies. It is found that this frequency can be detected in time histories of $u$ in the wake at the spanwise centre.A second configuration, consisting of a wall mounted cylinder with aspect ratio L/D = 25 is simulated in order to study the effect of introducing a no-slip surface. The effect on the end cell is found to be minimal, while the central cell shedding frequency is reduced. Comparisons with published data on a cylinder with aspect ratio L/D = 25 and two free ends shows that both the reduction of aspect ratio and the introduction of the no-slip boundary condition contributes to the reduced shedding frequency.

Abstract:
A stepped cylinder could be a desired design for an offshore buoy or SPAR platform. The geometry of a stepped cylinder consists of a small diameter cylinder (d) placed on top of a large diameter cylinder (D). This master thesis has investigated numerically the flow around a stepped cylinder with different diameter ratios (d/D) for a Reynolds number, ReD = 150. The commercial software Fluent v13.0 by Ansys was used for the numerical investigation.The aim of the study has been exploring the nearby wake flow as well as the region where the two cylinders are joined. The hydrodynamic forces and vortex shedding frequency have been analysed and compared for the four different diameter ratios: d/D = 0.3, 0.5, 0.8 and 0.9The major part of the published papers on the topic is based on experimental studies. Only two papers are based on numerical studies, having considered d/D = 0.5 exclusively. Earlier studies have focused mainly on vortex shedding in the wake flow, omitting the forces acting on the stepped cylinder.The stepped cylinder has been modelled using the software GAMBIT. A convergence study investigating the domain size and element density was conducted to ensure a grid independent solution. Special attention was directed at the step region to fully resolve the complex flow in this region. The numerical model was verified to be in good agreement with previous experimental- and numerical studies.For the stepped cylinders significant spanwise velocity was detected in the step region. For d/D = 0.3 and 0.5, upflow was detected over the leading edge of the step whereas downwash characterised the trailing edge of the step. Similarities to the flow around a finite length cylinder could be drawn for d/D = 0.3 and 0.5, whereas d/D = 0.8 and 0.9 resembled that of a straight cylinder.The step was found to affect the wake flow &#8776; 10D into D independent of diameter ratio. The wake flow behind the small diameter cylinder was less affected by the step than the large for d/D < 0.5. In the step region two distinct streamwise vortices were detected. A pair of edge vortices as well as a junction vortex were readily detected for d/D = 0.3 and 0.5. The junction vortex was not detected for d/D = 0.8 and 0.9 due to the small step change in diameter.The drag force on D was found to increase as d/D increased. Similarly, the amplitude of the lift force was also found to increase as d/D increased. The mean drag-coefficient varied along the span with peaks in the local drag-coefficient observed in close vicinity of the step.Regular spanwise vortex shedding was detected away from the step at a frequency similar to that of a straight cylinder. In the step region, located mainly on D, a cell of lower vortex shedding frequency was detected for d/D = 0.3 and 0.5. As d/D increased this cell seemed to disappear. Suppression of regular vortex shedding close to the step for d/D = 0.3 was observed for ReD = 150, 300 and 600. For ReD > 150 the large spanwise vortex structures were still discernible, but the presence of small-scale streamwise vortices complicated the flow.

Abstract:
Marine pipelines placed at or near the seabed are exposed to currents and waves. In the presence of a sedimentary seabed, the interaction between the surrounding water motions and the pipeline may cause erosion of sediments beneath the pipeline. Due to this erosion or due to the installation procedure, free spans may occur in sections along the span of the pipeline. A simplified description of the flow is obtained by approximating the seabed as a plane and impermeable wall. Most of the previous experimental and numerical studies on this flow are performed at Reynolds numbers, Re, in the range 103-105 as this range is of most relevance for offshore engineering purposes. Numerical modeling at such Reynolds numbers generally involves different kinds of artificial flow modeling. In this study, the software OpenFOAM is applied for numerical simulations of the viscous flow around a circular cylinder at Re= 100. At this Reynolds number the flow around an unconfined circular cylinder is characterized by vortex shedding and yet turbulence is avoided, which provides the possibility of accurate calculations of the flow. The flow is investigated with reference to visualizations of pressure, velocity and vorticity; and the flow characteristics are  quantified in terms of drag and lift acting on the cylinder and vortex shedding frequency. Numerical simulations of an unconfined cylinder in uniform cross-flow constitutes the basis of the present study, and these simulations are included in an attempt to validate the results and the applied computational method. The results for this flow are within the scatter of the reported values in the literature. In this study, the flow around a cylinder near a plane wall is of main interest. Three different gap ratios G/D=0:2;0:5;1:0 are applied. The results are generally in accordance with published data from numerical simulations; best agreement is found at G/D=0:2 and G/D= 0:5. The results are supportive to the suggestion of vortex shedding suppression to be caused by the interaction between the lee-side recirculating flow and the gap flow, which inhibits large-scale vortex roll-up. Further, the results at G/D= 1:0 indicates cancellation of opposite signed vorticity in the near-wall region, in accordance with suggestions in the literature. Additionally, the geometry of the wall is altered, introducing a hollow below the cylinder. This shape imitates a fully developed scour profile. These simulations are expected to bring new results to this topic of research. The flow is characterized by evident vortex shedding. Further, at this gap a distinct mean lift in the direction towards the wall is observed and both the drag coefficient and the frequency of vortex shedding is reduced as compared to the flow around a cylinder in uniform cross-flow. The obtained results exhibits similarity to published experimental data for the flow at Re= 1:104. Two-dimensional simulations are performed for all of the flow configurations, and a few three-dimensional simulations are performed for a cylinder in uniform cross-flow and a cylinder located a distance G/D= 0:5 from a plane wall. Due to the two-dimensional flow patterns, insignificant differences are found between the two-dimensional and three- dimensional simulations. In this study, emphasize is given to the influences on the solution of the following numerical parameters: time step, domain size, grid geometry, element size and element spacing. These parameters are thoroughly investigated in terms of convergence studies. Also included in this thesis is a review of some features of these flows and an overview of the governing equations, OpenFOAM and the applied solver icoFoam.

Abstract:
In this thesis, three-dimensional modelling of the flow around a circular cylinder isaccomplished. Two cases are considered. The first (Case 1) is a cylinder in steady,uniform current subjected to Reynolds number 3900. The second case (Case 2) isa cylinder in the vicinity of a rigid wall, also at Reynolds number 3900. For thesecond case, both a boundary layer velocity profile (Case 2a) and a uniform inletvelocity profile (Case 2b) is simulated. The gap-to-diameter ratio, e/D, is set to 0.2 for Case 2. Large eddy simulations (LES) with Smagorinsky subgrid scale (SGS)model are applied to simulate the flow. LES have ability to resolve fine structuresin the turbulent wake of the cylinder. A mesh convergence study is accomplishedfor Case 2a.In the first part of the thesis, the background theory for the case is given in addition to information about the applied pre- and postprocessing tools. In the lastpart of the thesis, the case set-up is described and the results are presented anddiscussed. Velocity profiles in the cylinder wake, hydrodynamic values and pressuredistribution on the cylinder wall are investigated to give a better understandingof the physics in the cases. The results are compared to published experimentalmeasurements and numerical studies.For the first case, the results tend to agree well with published research. The softwaresystem with LES and the Smagorinsky subgrid scale model does successfullysimulate the flow in the boundary layers, the shear layers and the near wake. Theresults are interesting in the context of flow bifurcation for at cylinder subjectedto Reynolds number 3900.The vortex shedding is suppressed for both Case 2a and Case 2b, as expected. Forthe cylinder in Case 2a, a decreased drag coefficient is observed when comparedto Case 1. This is not observed for the cylinder in Case 2b. The two cases areobserved to have an increased mean lift coefficient caused by the vicinity of the wall. However, for Case 2b, the increase is of larger magnitude. This is addressed to the pressure distribution on the cylinder surface. There are also observed differences in the wake statistics for Case 2a and Case 2b. It is concluded that both gap-todiameter ratio and boundary layer thickness have a significant influence on the flow around a circular cylinder.

Abstract:

The objective of the present study is to investigate the characteristics of a flow around a rotating circular cylinder with and without an end plate near a wall boundary. The different cases which are taken into consideration in the current investigations were with gap ratios of 0.1d, 0.5d, 1.0d, 1.5d and 2.0d. A symmetric end plate is attached behind the rotating circular cylinder at a distance of 0.1d from the cylinder and a gap ratio of 1.5d. We performed Computational Fluid Dynamics (CFD) simulation of the flow around a rotating circular cylinder near a plane wall boundary using a CFD solver, STAR-CCM+. Free-stream velocity is kept constant at 5 m/s and the Reynolds number calculated is 3.24X104. We then studied the flow characteristics such as lift and drag generated on the circular cylinder with and without an end plate and the wake structure. We observed that the vortex suppression is increased when the gap ratio is reduced, i.e., when the circular cylinder is nearer to the plane wall boundary. As the gap ratio increases the drag force generated decreases and the lift force increases considerably. In the case of rotating circular cylinder with an end plate, the wake area has moved upwards and the lift generated has increased manifold.

Abstract:
An experimental investigation was performed to study the structure of the flow field around finite circular and square cylinders in a water channel. Detailed velocity measurements using a particle image velocimetry (PIV) system and proper orthogonal decomposition (POD) analysis were conducted to examine the structures in the near-wake region. Iso-contours and profiles of mean velocities and some turbulent quantities at various streamwise locations were reported. The proper orthogonal decomposition was applied to provide insight into the structure of the flow. The results show that the vortex in the square cylinder is bigger and extends to cover part of the free end of the cylinder. There is also an up-wash flow from the base of the cylinders to form saddle points. The saddle point in the square cylinder is closer to the free end than in the circular cylinder. The low order reconstructed turbulent intensities from POD show that the square cylinder has more large scale structures than the circular cylinder.

Abstract:
A detailed study of oscillatory flow around two circular cylinders of different diameters is carried out numerically. The Reynolds-averaged Navier-Stokes equations are solved using a finite element method (FEM) with a k–ω turbulence closure. The numerical model is validated against oscillatory flows past a single circular cylinder where the experimental data are available in literature. Then it is employed to simulate the flow around two circular cylinders. It’s found that the fluid flow field around two cylinders is different from the single cylinder case, especially when the small cylinder diameter increases. The orientation of the small cylinder and the gap between two cylinders have significant effects on the vortex shedding process and force coefficients on the cylinders.

Abstract:
We measured the aerodynamic noise generated from an inclined circular cylinder with endplates in experimental conditions using a low noise wind tunnel. The inclination-angle dependency of the aerodynamic sound is related to the aspect ratio A that is the ratio of the distance between the endplates to the circular cylinder diameter. To analyze the dependency in detail we derived the correlation length from the velocity fluctuation in the wake. As a result, when the inclined angle changed from 0 degrees to 20 degrees, the correlation length got smaller at A = 10. On the other hand, in the case of A = 30, the correlation length got longer. So we visualized the flow around the cylinder using numerical simulation and the hydrogen bubble method in order to analyze these phenomena.
