Numerical Simulation of Liquid Tank Sloshing and Pressure Calculation based on Volume of Fluid Method

As a common phenomenon in liquid motions,sloshing usually happens partially in a filled liquid tank of moving ship.When coupling with ship motions it can cause violent motions and even capsizing under extreme conditions.At the same time,the sloshing of liquid tank is a complex liquid motions phenomenon which represent strong nonlinear and randomness.Based on the CFD software Fluent 6.3,under the force of single degree of freedom and multi-degree of freedom which would reflect in various range of the sloshing,the paper numerically simulated the different tank structures,calculated the pressure of monitor points and obtained the variation law of sloshing under stimulation.The effects of the different forms of liquid tank sloshing and variation trend are discussed.
