Abstract : Computational results of shock waves impinging on a truck-like target and the ensuing diffraction flowfield are presented. The Euler equations are solved with MacCormack's explicit finite difference scheme. Computed pressures on the surface of the model compare favorably with experimental results from shock tube experiments. Isopycnics for the diffraction phase are also presented and show the time-dependent development of vortices generated at the various corners of the model. (Author)
