63786 2025 eng lecture 0 -- -- -- A simple test bench was set up on the BAM test site to investigate shock waves caused by gas detonations. The aim was to build a simple mobile test bench that can be used for various applications, to demonstrate the vaildity and for comparison with other test benches. For this purpose a balloon filled with acetylene and oxygen at atmospheric pressure with an electric ignitor was used. The characteristics of the shock waves can be scaled via the gaseous mixture, the filling quantity of the balloon and the distance to the sensors. Pressure sensors were set up around the balloon at various distances to measure the shock. With the help of the high-speed recordings and the Rankine Hugoniot equations, the shock front pressure was estimated and compared with the results of the pressure sensors. In order to validate the results of this test bench, they were compared with an experiment using plastic explosive no. 4 . These agreed well with the results. Overall, symmetrical undisturbed scalable shock waves can be generated with the setup. Only the reproducibility, which is comparatively poor to open shock tubes due to the influence of wind, had to be improved. 35th International Symposium on Shock Waves (ISSW35) Brisbane, Australia 07.07.2025 11.07.2025 0 publish false true Marco Gerbeit eng uncontrolled Shock waves eng uncontrolled BOS eng uncontrolled Gas detonation Ingenieurwissenschaften und zugeordnete Tätigkeiten Chemische Verfahrenstechnik 2 Prozess- und Anlagensicherheit 2.1 Sicherheit von Energieträgern Infrastruktur Security Chemie und Prozesstechnik Datei im Netzwerk der BAM verfügbar ("Closed Access") Präsentation Anlagensicherheit und Prozesssimulation
