Abstract
Sloshing phenomena of liquid in a rectangular tank have been simulated by a CFD method, namely a large eddy simulation with standard Smagorinsky model. The free surface displacement was determined by solving the continuity equation for flow with unsteady moving boundary in the HSMAC iteration of determining the pressure and velocity. The calculated sloshing amplitudes are in good agreement with the experiment. The details of the sloshing phenomena, particularly the dynamic changes of the velocity and pressure distributions in the tank in forced oscillation could be studied effectively by a visual investigation.
