Supersonic flow at Mach number 2.0 is simulated over a half wedge using ANSYS CFD software for both viscous and inviscid flows. The formation of extra shock wave at the leading edge below the wedge is observed from the results of viscous analysis which supports previous research observations. Generation of this extra shock wave is further investigated using time-dependent numerical simulations. Boundary layer formation and the shock wave generation over the lower surface of the half wedge are studied from the unsteady analysis. From this study, it is investigated whether the formation of the boundary layer and the generation of the extra shock wave are interdependent. Time-dependent results showed that the formation of the boundary layer and the generation of extra shock wave are independent of each other.
