Numerical Study On Impact Pressure Due to Violent Sloshing Waves

Sloshing waves have received numerous studies over the past several decades. Nevertheless, there are still many uncertainties associated with wave breaking and splashing, formation of air pocket and air bubbles, behaviours of impact pressure and dynamic interaction between wave impact and structural response during violent sloshing. This paper will concentrate on impact pressure due to violent sloshing waves. The impact pressure will be investigated by using the MLPG_R (Meshless Local Petrove-Galerkin based on Rankine source solution) method, developed at City University London and the SPH (smoothed partial hydrodynamics) method, developed at Harbin Engineering University and also by using a commercial package – StarCD, which is based on finite volume method. Investigation will be performed for various cases with and without a baffle. Our main interest lies in the behaviours of impact pressure under different conditions, such as the relationship between the maximum pressure and the motion of the waves and effects of baffles. These behaviours are very relevant to analysis of structural responses and so to design of safe structures.
