numerical solution of the symmetric water impact of a wedge considering dynamic equations of motion

in this research, numerical simulation of a symmetric impact of a 2-d wedge, considering dynamic equations in two-phase flow is taken into account. 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 calculated and the results are compared with the results of the impact problem solved considering dynamic equations of the motion.
