Abstract:	The sloshing dynamics in a tank partially filled with liquid oil was simulated in this study. The formulation uses primitive variables on a staggered grid system for solving incompressible Navier-Stokes equations, which are subjected to the distortion of free surface. We made use of a volume of fluid technique to resolve numerical difficulties in association with nonlinear free-surface boundary conditions while a two-dimensional quadratic upwind advection scheme to deal with flux nonlinearities. Two problems, namely the free oscillation and the solitary wave propagation, have been chosen for benchmarking the method presented here. The liquid oscillations under conditions of resonance or nonresonance frequency in an oil tanker containing a perforated baffle plate have been studied extensively for two different liquid levels. Through this simulation, we have found that the degree of sloshing can be mitigated by these baffle plates.
