Prediction of pressure induced by large amplitude sloshing in a tank

A two-dimensional (2D) numerical simulation based on the volume of fluid (VOF) method is performed for predicting sloshing pressure in a partially filled liquid tank.For modeling impact pressure induced by large amplitude sloshing,an emphasis is given to the numerical treatment of the boundary conditions,which are sensitive to the simulation.Liquid sloshing inside a rectangular tank is simulated.The time history of the free surface position and the dynamic pressure are obtained.The results are compared with the test ones.These comparisons show that the present method can be used to simulate the load induced by large amplitude sloshing.
