Experimental study on sloshing and non-sloshing road cargoes dynamics
International Journal of Heavy Vehicle Systems, 2010This paper summarises the findings of an experimental investigation aimed at comparative evaluation of the modal response and rollover trends in sloshing and non-sloshing cargo vehicles, as a function of the fill level. A key point in the applied methodology is that cargoes present similar properties concerning their mass density and static position of

Nonlinear sloshing in zero gravity
Journal of Fluid Mechanics, 2002We study the effect of a time-periodic, lateral acceleration on the two-dimensional flow of a fluid with a free surface subject to surface tension, confined between two plane, parallel walls under conditions of zero gravity. We assume that the velocity of each contact line is a prescribed, single-valued function of the dynamic contact angle between

The Sloshing Motion of Cross‐Waves
Studies in Applied Mathematics, 1995Cross-waves are standing waves whose crests are perpendicular to the wavemaker, and they were first observed by Michael Faraday in 1831. The general phenomena of cross-waves is investigated in this paper using a multiple-scale perturbation method, and some numerical results are presented.

Numerical simulations of sloshing and suppressing sloshing using the optimization technology method
Applied Mathematics and Mechanics, 2018Sloshing is a common phenomenon in nature and industry, and it is important in many fields, such as marine engineering and aerospace engineering. To reduce the sloshing load on the side walls, the topology optimization and optimal control methods are used to design the shape of the board, which is fixed in the middle of the tank.

Update on SPHERES-Slosh for Acquisition of Liquid Slosh Data aboard the ISS
49th AIAA/ASME/SAE/ASEE Joint Propulsion Conference, 2013A current problem that severely affects the performance of spacecraft is related to slosh dynamics in liquid propellant tanks under microgravity conditions. The confidence in computational fluid dynamics (CFD) predictions are low because of the lack of benchmark against experimental data.

Sloshing-Coupled Ship Motion Algorithm for Estimation of Slosh-Induced Pressures
Journal of Marine Science and Application, 2018The effect of coupling between sloshing and ship motions in the evaluation of slosh-induced interior pressures is studied. The coupling between sloshing loads and ship motions is modelled through a hybrid algorithm which combines a potential flow solution based on transient Green function for the external ship hydrodynamics with a viscous flow solution

On the Sloshing of Liquid in a Flexible Tank
Journal of Applied Mechanics, 1958Abstract The kinetic and potential energies of an incompressible fluid having a free surface in a cylindrical tank subjected to translation, rotation, and simple bending are derived in the forms 1 2 ∑ i ∑ j m i j q . i q . j and 1 2 ∑ i ∑ j k i j q i q j where the qi (t) are generalized co-ordinates.

The ISS SPHERES-Slosh Experiment: Slosh Data Acquisition and Analysis
Journal of Spacecraft and RocketsAccurate prediction of liquid propellant slosh coupled with rocket launch vehicle or spacecraft dynamics requires computational fluid dynamics (CFD) models validated with long-duration, low-gravity slosh data. In a low-gravity environment, space vehicle disturbances, such as residual accelerations, orbital maneuvers, and docking, can induce propellant ...

On the piston and sloshing modes in moonpools
Journal of Fluid Mechanics, 2001So-called moonpools are vertical openings through the deck and hull of ships or barges, used for marine and offshore operations, such as pipe laying or recovery of drivers. In the present study, the author considers rectangular moonpools of large horizontal dimension.
