Abstract
Based on the Navier-Stokes equation, a numerical method is presented to simulate sloshing phenomena in a rectangular tank which is oscillated horizontally. A computational code is composed of the finite volume method using curve-linear boundary fitted coordinates, and the solution is solved by SIMPLE algorithm. In the numerical simulations with small water depths, the progressive waves with the beet are observed, and the surface displacement shows nonlinear responses. Numerical results are in good agreement with experiments, so the applicability of this code is shown. It is attempted to make clear understand the flow inside the sloshing tank using computer graphics and computational fluid dynamics. The flows are drawn by the velocity vectors, the streamlines, the color contour of pressure, and the vorticity using OpenGL. The streamlines are drawn by both stream function and the line integral convolution (LIC) method.
