Abstract

The interaction of an oblique shock with the bow shock in front of a hemisphere in Mach 14.6 flow is examined. The hypersonic laminar simulation is performed using a C++ code with the implementation of MPI written by the authors. The simulation is based on a set of experiments performed at the 48-inch Shock Tunnel at Calspan University at Buffalo Research Center (CUBRC). The Edney III interaction exhibits a statistically stationary behavior with dominant Strouhal number of 0.346. The surface pressure coefficient and dimensionless heat transfer are in general agreement with experiment; however, the location of the interaction of the incident shock with the bow shock is evidently slightly different than in the experiment. More calculations are in progress.
