Abstract

In this paper, a two-dimensional numerical simulation based on the Marker-and- Cell (MAC) method is used for the study of sloshing phenomena inside tanks of any shape. The free surface is treated according to a modification of the general MAC method developed at the University of Tokyo called TUMMAC. The impacts on the walls are studied by letting the time step free of reducing to cope with the high velocities appearing during the sloshing. Comparisons with experiments show a good agreement as far as the wave shape is concerned, the fluid viscosity seeming to be larger than expected since the wave amplitude looks underestimated. 1 Introduction The oscillations of fluid inside partially filled tanks, excited by the ship movements, are of great concern to structural designers, since sloshing loads can reach considerable
