Formation and Propagation Mechanisms of Diverging Gaseous Detonation Waves
Abstract
The unconfined gaseous detonation wave problem can be summarized in terms of three phenomenological aspects: initiation, global propagation and evolution of structure. The initiation aspect concerns the study of the mechanisms and immediate consequences of rapid energy transfer from a spatially localized source into a highly explosive gaseous medium. On the basis of source power density considerations the authors have successfully achieved correlation of a broad range of experimental results and are currently extending studies into the realm of ultra-short (picosecond laser spark) duration ignition. The global propagation and evolution of structure are determined by the local nonlinear coupling between chemical kinetics and hydrodynamics in the transient expanding flow field immediately behind the leading shock front.
