A numerical study has been carried out to investigate the flow field characteristics of a transonic compressible flow over a flat plate with backward facing step. The study has been performed by solving Two-Dimensional Navier-Stokes equations. The system of governing equations has been solved, using an explicit Harten-Yee Non- MUSCL Modified flux type TVD scheme and a zero-equation algebraic turbulence model to calculate the eddy viscosity coefficient. The results presented in this paper are computed for fixed step height, h = 7.5 mm and for different Mach numbers, M= 0.8, 1.0 and 1.2. The details on pressure, temperature and velocity field, together with recirculation length, expansion shock, reattached shock, interaction of shock wave are reported. The variations of flow field characteristics due to change of Mach number are also presented.
