Abstract
When a vessel containing a water is oscillated in the horizontal direction
with a external force, waves occurs on the water surface. This is called
as the sloshing phenomenon. This paper describes the application of the
Trefftz-type boundary element method to the simulation of the sloshing
phenomenon.
Assuming that the fluid could be the perfect fluid, the phenomenon can
be modeled as the initial and the boundary values problem of the Laplace
equation with respect to the velocity potential. The governing equation
is firstly solved with the boundary conditions to determine the velocity
components on the fluid surface. The surface is moved according to the
surface velocity at each time step. One of the most important part of this
process is to accurately estimate the velo
