Abstract

In this article, RIGID WEDGE water entry problem under different conditions is evaluated using numerical scheme RIGID WEDGE water entry continues to be one of the fundamental issues raised in the hydrodynamics studies and is known as a reference for the study of slamming phenomena. The exact calculation of the pressure caused by the slamming phenomenon can be used to analyze the appropriate structural analysis of the ships. In the current study, important variables such as speed and fluid pressure are investigated using computational fluid dynamics method based on the open source Open FOAM code by numerical solution of the governing equations of tow phase fluid. In order to verify the simulation results obtained from this research, Tthe values of the maximum pressure and the location and exact time of its occurrence and also PRESSURE COEFFICIENT distribution at the impact region have been compared by experimental results of other studies. These investigations have been utilized at different impact velocities and angles. By comparing the numerical results and experimental values, an error was found in the range of 2% to 9%. In addition, variables affecting the pressure applied to the wedge such as water entry velocity and different DEADRISE ANGLEs have been studied.
