Sloshing waves in moving tanks have been studied numerically, theoretically and experimentally in the past several decades. Most reported studies have been for tanks excited by forcing motion in a limited number of directions and with fixed excitation frequencies throughout the forcing. In the present study, a time-independent finite difference method is used to simulate fluid sloshing in the t...

We consider the problem of the active reduction of structural vibrations of a plane wing induced by the sloshing of large masses of fuel inside partly full tank. This study focuses on an experimental device composed of an aluminum rectangular plate equipped with piezoelectric patches at the clamped end and with a cylindrical tip-tank, more or less filled with liquid at the opposite free end. Th...

Trapped modes in the linearised water-wave problem are free oscillations of an unbounded fluid with a free surface that have finite energy. It is known that such modes may be supported by particular fixed structures, and also by certain freely-floating structures in which case there is, in general, a coupled motion of the fluid and structure; these two types of mode are referred to respectively...

The tank is one of the most important components in train which serves as a place to store fuel. However, so far has been component that gone unnoticed, even though there very issue consider, namely how fluid moves due movement while moving. free liquid called sloshing. Sloshing can be reduced by adding anti-sloshing baffles. So it necessary simulate sloshing taking into account value vehicle s...

Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of  rigid and padded wall tanks in terms of the wave elevat...

The thrust vector control problem for an upper-stage rocket with propellant slosh dynamics is considered. The control inputs are defined by the gimbal deflection angle of a main engine and a pitchingmoment about the center of mass of the spacecraft. The rocket acceleration due to themain engine thrust is assumed to be large enough so that surface tension forces do not significantly affect the p...

The double-row and double-chamfered aquaculture tank is a special structure of the ship. sloshing this coupled with hull motion, which has an important impact on safety motion. In present study, research motion response ships was conducted based model seakeeping tests in regular waves. test results were compared numerical simulation solid loading without sloshing. showed that pitch consistent a...

:האצרהה ריצקת להל Liquid-filled tanks are widely used in various branches of engineering, including nuclear, process and aerospace industries, for storage of chemicals, gasoline, water, and different hazardous liquids. Dynamic stresses in such tanks develop due to various external effects that might lead to strongly nonlinear or even impact-like sloshing regimes, such as high-amplitude oscilla...

We propose a control design scheme that aims to prevent undesirable liquid outpouring and suppress sloshing during the forward and backward tilting phases of the pouring process, for the case of liquid containers carried by manipulators. The proposed scheme combines a partial inverse dynamics controller with a PID controller, tuned with the use of a “metaheuristic” search algorithm. The “metahe...

The disturbance on the free surface of the liquid when the liquid-filled tanks are excited is called sloshing. This paper examines the nonlinear sloshing response of the liquid free surface in partially filled two-dimensional rectangular tanks using finite element method. The liquid is assumed to be inviscid, irrotational, and incompressible; fully nonlinear potential wave theory is considered ...
