Numerical Simulation of Two Dimensional Dynamic Motion of the Symmetric Water Impact of a Wedge

In this research, a numerical simulation of a symmetric impact of a 2-D wedge, considering rigid body dynamic equations of motion in two-phase flow is presented. The two-phase flow around the wedge is solved based on finite volume method and Volume Of Fluid (VOF) scheme. The dynamic mesh model is used to simulate dynamic motion of the wedge, thereby; the effects of different dynamic meshes in both structured and unstructured meshes in simulating symmetric water impact phenomenon are investigated. Moreover, the effects of flow turbulence and fluid compressibility at the moment of water impact are studied. Also, the effects of different deadrise angles and body mass on the slamming force are investigated. At last, the impact problem of a wedge with constant velocity is solved and the results are compared with those calculated by considering dynamic equations of the motion.
