Air entering the engine of a supersonic aircraft must be slowed to subsonic speeds for the engine to perform properly and not become significantly damaged over time. Diffusers are designed to create a shockwave to slow down air to subsonic speeds before the air enters the engine. This project will focus on the numerical analysis and design of diffuser geometries for supersonic aircraft engines. The main objective is to evaluate supersonic flow over different geometries, specifically the interaction between shock waves and boundary layer, and to minimize the amount of drag created by different diffuser geometries to optimize the efficiency of the diffuser.
