Abstract
An experimental study is conducted to investigate the effect of the diaphragm thickness on the transmission of an incident detonation wave from a propane–oxygen mixture (donor) to a propane-air mixture (acceptor). Quenching of the incident detonation wave near the interface is observed for all test cases. The presence of a diaphragm results in a longer distance required for re-initiating the detonation wave in the acceptor. In the presence of a diaphragm with a thickness smaller than 50 μm, the velocity of detonation wave propagation approaches that of the test case with a slide gate valve (no diaphragm).
