Abstract
In this research, we presented a simulation model based on hexahedral mesh, Laminar and Volume of fluid (VOF) flow models to predict the better groove pattern of transmission clutch plate. Significance of Hexahedral (Hex) mesh over Polyhedral-Prism layer (PPL) mesh model has been explained as well. Simulation results reflect close similarity with the test results. The difference of drag torque characteristics for different groove shape has been explained via particle tracking and scalar plots. Test and simulation results show that around 50% drag loss reduction is possible by effective design of the grooves. Therefore, our proposed simulation model offers a cost-effective and time-saving means to select the best groove profile and optimize the groove shape to minimize transmission drag loss
