The paper presents several 2D and 3D CFD simulations to understand the shock wave and reflected shock waves evolution at the entrance of a scramjet engine. Pressure, temperature and Mach number fields are introduced and compared when using different turbulence models, the information obtained via CFD is employed to modify the existing two dimensional theory. Comparison between the 2D and 3D CFD results clarify which is the expected fluid evolution inside the engine and the shortcomings associated to the 2D models.
