In this paper, the liquid sloshing in 2-D baffled tank is simulated and compared. In the Arbitrary Lagrangian-Eulerian (ALE) method, the full Navier-Stokes equations are employed. In the boundary element method (BEM), the liquid in the tank is assumed to be potential. Both methods are firstly compared with the available analytical solution for liquid sloshing in a tank without baffles. Good agreement is obtained. The liquid sloshing with rigid baffles is investigated through the compar-ison of the two methods. The effects of the baffle parameters such as dimension and position on slosh-ing are provided. The dynamic force and moment acting on the tank are also computed.
