ANALYSIS OF INITIATION OF DETONATION PROCESS IN A SYSTEM COMPRISING AN EXPLOSIVELY LOADED ELASTIC PARTITION

摘要

A mathematical-physical-numerical model has been created to describe the phenomena accompanying the initiation of a detonation process in an explosive mixture by means of a nonstationary shock wave generated by an explosively driven inertial partition with elastic properties. As a result of an analysis of those phenomena the time and place of initiation of a detonation in 2H_2+O_2 mixture have been determined on the basis of a series of computer simulations, as a function of density of the gaseous mixture and the thickness of the inert partition. The phenomena accompanying the initiation of detonation process have been described with special consideration of the retonation phenomenon in gaseous explosive mixtures.
