Kurzfassung
In the frame of the project "Gasdynamically initiated nanoparticle production", detailed numerical and experimental investigations of pseudo-shock systems in a Laval nozzle with parallel side walls have been carried out. The location of the pseudo-shock system is defined in this system of two chocked Laval nozzles by the ratio of the critical cross sections A2*/A1*, the stagnation pressure loss across the shock system and viscous losses. The wall pressure distributions and high velocity Schlieren videos recorded in the experiments are compared to the results of a steady and an unsteady numerical simulation. Corresponding results have been found.
