Abstract:
An experimental and analytical study was conducted to determine the liquid natural frequencies and the resultant slosh forces in horizontal cylindrical tanks. This paper presents a study of the liquid slosh response of the small and the large slosh wave heights. In the former case, an effective calculation method of the longitudinal slosh response is presented by substituting an equivalent rectangular tank for a horizontal cylindrical tank. The calculated natural frequencies, slosh wave heights and slosh forces are in good agreement with the experimental ones. The transverse slosh response is also discussed. In the latter case, impulsive slosh forces were observed for longitudinal excitation, when the slosh liquid hit the top of the tank. The measured slosh forces including the impulsive forces were larger than the calculated ones. In order to determine the maximum slosh force, the experiments were parametrically conducted with several tank aspect ratios, liquid levels and excitation amplitudes. The obtained maximum slosh forces for longitudinal and transverse direction were about 0.28 and 0.16 times the full liquid weight of the tank, respectively.

Abstract:
<span>Conventionally, the control of liquid slosh system is done based on model-based techniques that challenging to implement practically because of the chaotic motion of fluid in the container. The aim of this article is to develop the tuning technique for model-free PID with derivative filter (PIDF) parameters for liquid slosh suppression system based on particle swarm optimization (PSO). PSO algorithm is responsible to find the optimal values for PIDF parameters based on fitness functions which are Sum Squared Error (SSE) and Sum Absolute Error (SAE) of the cart position and liquid slosh angle response. The modelling of liquid slosh in lateral movement is considered to justify the design of control scheme. The PSO tuning method is compared by heuristic tuning method in order to show the effectiveness of the proposed tuning approach. The performance evaluations of the proposed tuning method are based on the ability of the tank to follow the input in horizontal motion and liquid slosh level reduction in time domain. Based on the simulation results, the suggested tuning method is capable to reduce the liquid slosh level in the same time produces fast input tracking of the tank without precisely model the chaotic motion of the fluid.</span>

Abstract:
The movement of the liquid cargo within a partly filled tank car is known to impose additional slosh forces and moments that may adversely affect the dynamic responses of the vehicle. This study is aimed at analyzing the liquid cargo slosh in a partly filled tank car and its effects on vehicle responses during a switch-passing maneuver. A two-dimensional analytical liquid slosh model is formulated for the analyses of the liquid load shift in the roll plane, lateral slosh force, and roll moment through summation of first four antisymmetric modes of the liquid. The analytical slosh model is integrated to a 114 degrees-of-freedom multibody dynamic model of the railway tank car comprising nonlinear wheel–rail contact and contact pairs of the suspension system. The validity of the slosh model is illustrated by comparing the responses with those reported in other studies and those obtained from a nonlinear computational fluid dynamic model. The coupled fluid–vehicle model is subsequently used to study the effects of fluid slosh during switch-passing maneuvers on different response measures, namely roll motion of the tank car, lateral and vertical wheel–rail contact forces, and derailment ratio. The significance of the liquid cargo slosh in the partially filled state is demonstrated by comparing the responses with those of the car with equivalent rigid cargo. The results show that liquid sloshing within the partly filled car can lead to higher magnitudes of car body roll angle and thereby the unloading ratio compared to the conventional rigid cargo car. Switch-passing critical speeds are further identified for different fill ratios and switch geometries. For fill ratios below 80%, the switch-passing critical speeds of the partly filled car are substantially lower compared to those of the equivalent rigid cargo car. Neglecting the contributions due to dynamic slosh force and roll moment arising from a partially filled railway tank car may thus lead to underestimation of the critical speed in switch-passing maneuvers.

Abstract:
The behavior of sloshing dynamics modulated fluid systems driven by the orbital accelerations including gravity gradient and jitter accelerations have been studied. Partially liquid-filled rotating dewar applicable to a full-scale Gravity Probe-B Spacecraft container with and without baffle are considered. Results show that slosh waves excited along the liquid-vapor interface induced by gravity gradient dominated orbital accelerations provide torsional moment with tidal motion of bubble oscillations in the rotating dewar. Fluctuations of slosh reaction forces and torques exerted on the dewar wall driven by the orbital accelerations are also investigated. Since the viscous force between a liquid-solid interface, and the surface tension force between a liquid-vapor-solid interface can greatly contribute to the damping effect of slosh wave excitation, a rotating dewar with baffle provides more areas of liquid-solid and liquid-vapor-solid interfaces than that of rotating Dewar without the baffle. Results show that the damping effect provided by baffle reduces the amplitudes of slosh reactions forces and torques feedback from the fluids to the container, in particular, the components of fluctuations transverse to the direction of baffle.

Abstract:
We have used electrical capacitance tomography (ECT) to instrument a demonstration tank containing kerosene and have successfully demonstrated that ECT can, in real time, (i) measure propellant mass to better than 1% of total in a range of gravity fields, (ii) image propellant distribution, and (iii) accurately track propellant centre of mass (CoM). We have shown that the ability to track CoM enables the determination of slosh forces, and we argue that this will result in disruptive changes in a propellant tank design and use in a spacecraft. Ground testing together with real-time slosh force data will allow an improved tank design to minimize and mitigate slosh forces, while at the same time keeping the tank mass to a minimum. Fully instrumented Smart Tanks will be able to provide force vector inputs to a spacecraft inertial navigation system; this in turn will (i) eliminate or reduce navigational errors, (ii) reduce wait time for uncertain slosh settling, since actual slosh forces will be known, and (iii) simplify slosh control hardware, hence reducing overall mass. ECT may be well suited to space borne liquid measurement applications. Measurements are independent of and unaffected by orientation or levels of g. The electronics and sensor arrays can be low in mass, and critically, the technique does not dissipate heat into the propellant, which makes it intrinsically safe and suitable for cryogenic liquids. Because of the limitations of operating in earth-bound gravity, it has not been possible to check the exact numerical accuracy of the slosh force acting on the vessel. We are therefore in the process of undertaking a further project to (i) build a prototype integrated “Smart Tank for Space”, (ii) undertake slosh tests in zero or microgravity, (iii) develop the system for commercial ground testing, and (iv) qualify ECT for use in space.

Abstract:
An efficient methodology is proposed for simulation of roll dynamics of a tank vehicle system coupled with transient hydrodynamic forces due to fluid slosh. The transient fluid slosh in a horizontal cylindrical tank is analytically modeled considering simultaneous lateral, vertical and roll excitations assuming potential flows and a linearized free-surface boundary condition. For this purpose, the fluid domain in the Cartesian coordinate system is transformed to the bipolar coordinates, where the Laplace equation could be solved using separation of variables. The resulting hydrodynamic pressure, free-surface elevation and slosh force and roll moment are formulated in the tank-fixed coordinate system. The transient fluid slosh model is subsequently integrated to a dynamic roll plane model of a tank vehicle combination to investigate the effect of transient liquid slosh on the roll stability of the vehicle during steady-turning as well as path-change maneuvers. The analyses are performed for different fluid fill heights considering both variable and constant cargo load conditions. The results suggest that the roll stability of tank vehicles can be efficiently analyzed using the coupled linear slosh and multi-body vehicle models with significantly lower computational effort than the methods employing computational fluid dynamic fluid slosh models.

Abstract:
A study of the liquid behaviour in horizontal cylindrical road containers undergoing a steady turning manoeuvre is presented and discussed. The steady state solutions are derived analytically from the hydrostatic equations. The transient solutions are obtained by numerical integration of the Navier-Stokes, continuity and free-surface equations. The non-dimensional governing equations are solved in primitive variables by using a modified marker-and-cell technique which involves the interpolation-reflection type boundary conditions developed for this investigation. The mathematical model of the liquid motion includes all essential non-linear effects and allows the damped natural frequencies of liquid vibrations to be obtained as well as the magnitudes of the liquid slosh loads. This study also enables the coupled directional dynamics of the ‘vehicle-liquid tank’ system undergoing different road manoeuvres to be investigated by integrating the non-linear fluid slosh model and an appropriate vehicle model simultaneously.

The rigid slug method for modelling sloshing liquid fuel aboard dual-spin stabilized spacecraft has been shown to be inadequate by recent flight data. This rigid slug model and a uniform gravity model put forth by Abramson is examined in detail. The Abramson model is incorporated into a computer simulation written specifically to predict spacecraft attitude. An analysis is performed with both the modified and unmodified versions of this simulation to determine the boundaries of stability for rotor and platform asymmetries. The results show that the improved model is better able to predict spacecraft attitude stability.

Abstract:

The aim of the thesis has been to study methods to minimize the slosh when moving liquid-filled packages in packaging machines. An automatic method for generation of the movement of a package in a packaging machine is of growing importance. The main reason is that reduced slosh leads to increased production rate. Progress within measurement technology creates possibilities for new solutions. One purpose has been to find methods and equipment to detect the height of the wave, perhaps at several places or alternatively the entire liquid surface shape. When suitable equipment for detection of the wave movements was found, collected measurements were analyzed and criteria for describing improvements of the slosh properties have been formulated.

Initially a sensor specification was written in order to simplify the search for suitable equipment. Sources of information have mainly been catalogues and Internet. The search resulted in that a number of sensors were borrowed for tests. The results of the tests supported the choice of the most suitable sensor, in this case a laser sensor. The main reason is that the sensors detection ability is good compared to its price. An analysis of the sensors most important properties confirmed the choice of the laser sensor. To be able to compare waves, criteria for what is considered to be good wave properties have been formulated and evaluated.

The work has confirmed that it is difficult to find a simple and cheap solution for wave detection given that the solution should have good detection ability. It has also been difficult to formulate simple but working criteria for wave performance, and this has led to a compromise between the complexity of the criterion functions and the result of the wave score. Ideas about how an automatic method, based on the chosen sensor and the criterion functions, can be implemented, have been introduced. During the work, some interesting discoveries have been made. These have led to better understanding of how some parameters should be chosen, to better understanding of wave movements and to better choice of future work.

Abstract:
In this thesis, the problem of suppressing sloshing dynamics for the linear movement of a cylindrical or rectangular container is addressed by designing proper control laws able to compute position, velocity and acceleration. In this research, sloshing is considered a vibration suppression problem for a second order system, and the newly controlled output dynamic allows the liquid inside the container to move with significantly less oscillation. The approximate mathematical model used to describe the liquid slosh is a linear damped pendulum. With this model, two different control techniques are designed, simulated and implemented on a real platform. The benefits and advantages of the proposed control laws are widely discussed and demonstrated with several tests in which a vision system is used to validate and confirm the differences between the controlled and non-controlled system. This thesis was developed in collaboration with Beckhoff Automation, and the tests were carried out using Beckhoff resources. In particular, hardware and the innovative drive technology, the XTS transport system, were employed.

Abstract:

Today, autoinjectors are developed for more viscous drug solutions, which require larger forces for actuating the syringe and impose larger stresses on the drug solution during the administration of autoinjectors. We developed experimentally validated high-fidelity simulations to investigate the liquid jet formation, liquid slosh and cavitation during the insertion process of an autoinjector.
The jet formed due to an acceleration-deceleration motion of syringe is found to be governed by the interplay between inertial, viscous, surface tension and gravitational forces. A scaling for the jet velocity and a criterion for the jet breakup in a simplified geometry are proposed.
When the syringe accelerates and decelerates during the insertion, liquid slosh occurs and there is a vehement motion of the air-liquid interface. Here, we quantified the area of air-liquid interface and hydrodynamic strain rate, which increase with the air gap size, syringe velocity, tilt angle and inner wall hydrophobicity, and decrease with the solution viscosity and hardly change with the liquid column height and surface tension. The strain rate is not sufficient to unfold the protein and the air-liquid interface is more likely to cause protein aggregation.
In a spring-driven autoinjector, the plunger is actuated by the impact of a driving rod, which generates a strong pressure wave and can cause cavitation inception. The cavtiation bubbles can be impeded by the syringe walls and form a re-entrant jet shooting toward the syringe wall. During the process, the protein molecules are focused in the jet, pushed toward the syringe wall and spread across the wall, which can be the reason for the protein aggregation and adsorption on the syringe walls. The impedance effects of the wall decreases with the wall distance and increases with the maximum bubble size. The maximum bubble radius also increases with the liquid column size and nucleus size and decreases with the air gap pressure. Since inertia effects dominate in the cavitation process, the liquid viscosity and surface tension hardly changes the cavitation bubble dynamics. Small bubbles can also form in the bulk, which may generate aggregates in the bulk solution. Bubbles in the cavitation bubble cloud may coalesce with nearby bubbles and induce a higher pressure at the collapse (up to 1000 bar). This high pressure can potentially generate hydroxyl radicals that oxidize the protein molecules.
The current study presents a detailed picture of fluid flows in autoinjectors and provide recommendations for mitigating the liquid slosh and cavitation generated in syringes. The results can be combined with future experiments to understand the implications of fluid flows on protein drugs and the performance of autoinjectors.

Abstract:
Liquid cargo contained in a partly-filled tank is known to experience the sloshing movement when subjected to manoeuvre-induced disturbances. Large amplitude slosh can be induced within a partly-filled road tank vehicle under mild to severe directional manoeuvres, which could severely degrade the vehicle stability and directional control limits. A three-dimensional computational fluid dynamics slosh model is implemented for the partly-filled cleanbore and baffled tanks on the basis of the Navier-Stokes equations incorporating the VOF technique. A comprehensive experimental study is conducted to analyze the fluid slosh within a scale model tank with and without the baffles under continuous as well as single-cycle sinusoidal lateral and longitudinal acceleration excitations. The three-dimensional fluid slosh responses are further investigated for full scale baffled and unbaffled vehicle tanks using the validated fluid slosh model. The fluid slosh characteristics are analyzed under different fill volumes corresponding to a constant load and subjected to excitations representing steady-turning, straight-line braking, braking-in-turn and path change maneuvers. The fluid slosh analyses are also carried out to explore the anti-slosh effectiveness of baffles and to evaluate the effects of baffle design factors, such as equalizer and the orifice size. The influences of transient fluid slosh on the tank vehicle stability and responses are studied by incorporating the fluid slosh model to in-plane vehicle models. The two-dimensional roll-plane slosh models of partly-filled tanks of different cross-sections are integrated with the roll moment equilibrium of an articulated vehicle to derive the vehicle roll stability limits. The roll stability analyses are performed for circular and "Reuleaux triangular" tanks under the conditions of constant and variable cargo loads. The results attained are compared with the quasi-static solutions to demonstrate the role of transient slosh loads on the roll stability limits. The three-dimensional slosh model of a partly-filled tank is also integrated into a 7-DOF pitch plane model of a tridem truck to analyze its straight-line braking characteristics in the presence of fluid slosh. The straight-line braking responses of the coupled tank-vehicle model with and without baffles are analyzed under different fill volumes but constant load for different magnitudes of braking treadle pressure and road surface adhesion limits

Full text
Abstract:
The liquid motion within a partially filled moving container has been associated with reduced overturning limits and braking efficiency of highway tank trucks. While the studies using quasi-static models have evaluated the contribution of cargo displacement in degrading the stability characteristics of tank trucks, the role of transient load surges on the directional stability and safety measures has been ignored. It has been suggested that the transient fluid slosh and fluid-structure interactions may further reduce the stability limits of the vehicle. This dissertation work focuses on various dynamic response measures of the dynamic liquid slosh in a partially filled circular-cross section tank exposed to the lateral, longitudinal, a combination of lateral and longitudinal acceleration excitations. The analysis of a partially filled clean bore circular tank is performed under different magnitudes of steady as well as harmonic lateral acceleration fields using the FLUENT software. The measures include the dynamic variations in forces, moments, centre of mass coordinates and mass moments of inertia of the cargo, which could be applied to assess the direction performance of vehicles subject to transient fluid slosh. The results are compared with those derived from the quasi-static liquid slosh model and the significance of the dynamic slosh behaviors is discussed as functions of the fill level, magnitude of acceleration, physical properties of the liquid cargo. A relationship between the lateral force and the resulting roll moment is derived, which suggests that the roll moment could be defined as a function of the horizontal force and tank radius.

Abstract:
This chapter extends from the previous, further examining police service delivery with respect to Lakeside’s business community. The authors open with a discussion of the Lakeside Boosters, a police charity where corporations can sponsor CPAB-led events and programs or provide general use funds. The Business Car is the primary unit responsible for all business relations, however SLOs regularly patrol these establishments in the course of their patrol routines. The chapter follows SLO Phil Hackett as he regulates the racial and moral boundaries of local liquor store patrons and sees SLO Marge Sierra advocate for the deservingness of a new 7-Eleven convenience store in the neighborhood, despite public resistance, because its corporate ties ensure elevated security and regulation. She contrasts this store with the area’s Black-owned businesses, whose continuing closures signal a positive shift for the maintenance of social order. The Lakeside Division’s relationship with local businesses, as the authors found, was not unusual. Rather, this is a normative institutional alignment. Coupling community policing with LA’s post-1992 urban redevelopment scheme, Rebuild Los Angeles, ensures that divisions can support local enforcement strategies in a time of declining city budgets, while also maintaining a hospitable environment for business growth.

Abstract:
This study is aimed at analysis of transient lateral slosh in a partially-filled cylindrical tank with different designs of longitudinal partial baffles using a coupled multimodal and boundary-element method. A boundary element method is initially formulated to solve the eigenvalue problem of free liquid slosh, assuming inviscid, incompressible and irrotational flows. Significant improvement in computational time is achieved by reducing the generalized eigenvalue problem to a standard one involving only the velocity potentials on the half free-surface length using the zoning method. The generalized coordinates of the free-surface oscillations under a lateral excitation are then obtained from superposition of the natural slosh modes. The lateral slosh force is also formulated in terms of the generalized coordinates and hydrodynamic coefficients. The validity of the model is illustrated through comparisons with available analytical solutions. Two different designs of longitudinal baffles are considered: bottom- and top-mounted baffles. The effect of different baffle designs on the normalized slosh frequencies, modes and lateral force are investigated. It is shown that the multimodal method yields computationally efficient solutions of liquid slosh within moving baffled containers. The results suggest that the effectiveness of baffles in suppressing the liquid oscillations is strongly affected by the baffle length relative to the free-surface height. The top-mounted baffle yields the greatest effectiveness, when it pierces the free-surface. The bottom-mounted baffle, however, may not be considered as an efficient mean for controlling the liquid slosh in tank vehicles where the liquid fill height is above 50%.

Abstract:
The slosh frequencies of liquid in a liquid-filled cylindrical tank, made of laminated composites, are investigated in the present paper. An annular laminated plate is used as a baffle, which is fitted to the inner periphery of a cylindrical tank. Finite element codes are accordingly developed and are then used to analyze both the liquid domain and the structural domain i.e., the tank and the baffle. The slosh frequencies of liquid are computed for different dimensions and positions of the baffle. The coupled vibration frequencies of the tank-baffle system are computed considering the effect of sloshing of liquid. The asymmetric modes corresponding to circumferential wave number one are studied in the present investigation. The results obtained for a liquid filled elastic isotropic tank without baffle and a rigid tank with rigid baffle are compared with the available results, and they are found to be in good agreement. The results for composite tanks cover the effects of a wide range of parameters including composite baffles as well as different lamination schemes and number of layers of the tank wall on the slosh frequencies and coupled vibration frequencies.
