Abstract: Numerical simulations of three-dimensional viscous liquid sloshing in rectangular containers were carried out using an improved volume of fluid technique in conjunction with the Navier-Stokes Equations. The present study is to investigate, numerically, the relative effectiveness of passive (fixed) baffles and active (moving) baffles for control of liquid sloshing. Both the deep water case and the shallow water case were studied. The study showed that active control of liquid sloshing, using moving baffles with feedback mechanisms, can be very effective in suppressing large amplitude sloshing.
