Kurzfassung
During previous investigations on pseudo-shock systems we have observed reproducible differences between measurement and simulations for the pressure distribution as well as for size and shape of the pseudo-shock system. A systematic analysis of the deviations leads to the conclusion that small gaps of delta z = O(10^−4) m between quartz-glass side walls and the metal contour of the test section are responsible for this mismatch. The focus of the present study is put on a numerical analysis of the interaction between gap-flow and shock oscillation. Furthermore, the impact of gaps on the occurrence of shock asymmetry is discussed.
