Lubrication plays a crucial role in enhancing the efficiency and durability of automotive gear systems by minimizing friction, wear, and heat generation. This study investigates gear lubrication using Computational Fluid Dynamics (CFD) simulations with Simerics MP+ software, focusing on validating its accuracy for various lubrication methods. The primary objective was to evaluate the performance of forced lubrication systems by examining key parameters such as mesh resolution, time step, oil jet position, and volumetric flow rate through a series of sensitivity analyses. To validate the simulation results, a comprehensive physical experiment was designed along with its components to replicate the simulated conditions.
