In this paper, the new concept of shock/shock and shock/boundary layer interactions at hypersonic flow, i.e Type IVr Interaction has been analyzed. The investigation is restricted to stream at Mach 9 around a two-fold wedge chose to produce an interaction of type IVr that does not fit into Edney's (I-VI) order. It is generally known that the interaction of type IV is associated with very high local loads in pressure and heat transfer. The numerical goals of the Navier Stokes conditions permit the forecast of the structure of stream fields like shear layer, expansion fan, slip line, adverse pressure gradient, and separation bubble. The numerical method used is based upon a finite-volume formulation defined on a structured mesh, and analysis is carried out through linear and non-Linear Eddy Viscous Methods. Unlike other interactions held by Edney, the Type-IVr is completely contradicting the flow phenomena obtained during and after the interaction region. Interaction took place in the first wedge itself and the Supersonic Jet will continue three fourth along with the second wedge. The flow will be transonic exactly at the wedge. Specific accentuation is given to the commitment of Reynolds number on the topological qualities and dynamic structure of the stream field. A comparative analysis of the contours and vectors of Mach number, Skin friction, and pressure co-efficient is shown. The results acquired and indicated that the flow field is exceptionally delicate to disturbance impacts.
