Simulation der Druckwellenausbreitung in verzweigten Kanälen mit dem SHARC Code

The propagation of shock and blast waves in branched ducts was investigated by the SHARC code. The results from the simulation of shock wave propagation were compared with experimental data. It can be seen that there is good agreement of experiment and simulation. There are no experimental data for blast wave propagation to compare with. The created blast waves had a defined peak pressure and negative pressure phase. It is possible to determine the drop of peak pressure and the increase of the positive pressure duration during the propagation by simulation.
