Abstract : A numerical analysis of a supersonic, inviscid, steady flow past a blunt-nosed cone at yaw is presented. The numerical technique is suitable only for shockless flows. The purpose of the paper is twofold: to show how accurate results can be obtained with a coarse computational mesh and short running times, and discuss the physical evolution of the flow from a blunt-body pattern to a conical pattern. The formation of a vortical layer is followed in detail. Asymptotic results are compared with the results of an independent calculation for pointed cones. (Author)
