REINITIATION IN DIFFRACTING MULTIFRONT DETONATIONS

The basic results of experimental studies on reinitiation in diffracti ng multifront detonation waves (DW) are presented for various symmetri es and fuel-oxygen and fuel-air mixtures (including those diluted with inert gases). Characteristic parameters are identified for each diffr action pattern. The physical processes taking place directly in the DW front govern reinitiation. The most important of these processes are collisions of transverse waves which serve as a kind of microscopic in itiators.
