| Abstract | A series of numerical simulations supported by experiments are reported on the interaction between a planar incident shock and a single rectangular obstacle. The dynamics of the interaction are described, particularly the reflection of the incident shock and the onset or otherwise of detonation. The test mixtures used were stoichiometric hydrogen and oxygen diluted with either argon or nitrogen, at an initial pressure of 5.3 kPa. The aim of the study was to determine the conditions under which a reflected detonation was generated. Predicted and observed critical conditions are compared with a simple criterion based on the auto-ignition delay time behind an ideal reflected shock and the acoustic transit time across the face of the obstacle. The physical and chemical processes that have been observed are also discussed. |
