Abstract : The interaction of oblique shock waves of different intensities in a hypersonic flow both from the theoretical and experimental viewpoints is investigated. The primary purpose of this study is to predict the angle with respect to the free stream flow direction of the vortex layer or contact surface which is generated by this interaction phenomena. Theoretical inviscid and vis cous solutions were programmed on the IBM 7090 computer for a range of Mach numbers from 6 to 20 and a range of flow deflection angles between 2 degrees and 30 degrees. In addition, empirical relations are developed to predict this contact surface angle with a minimum of computation, if a high degree of accuracy is not required. The three methods of solution are then compared and recommendations made as to under what conditions each is applicable. In addition, the effect of the variation of the various flow and geometric parameters on the viscous solution is considered. (Author)
