Time Dependent Studies of Reactive Shocks in the Gas Phase

Abstract

The coupling of the hydrodynamics and the chemical kinetics in a reactive mixture ignited by the passage of a shock is examined using a time- dependent numerical model. The fluid dynamic and chemical rate equations are integrated self-consistently on their own characteristic time-scale using the flux-corrected transport and selected asymptotic methods, respectively. Results are presented for a shock in an H2-O2 mixture. The detailed calculations of the chemical and fluid structure of the shocked region show clearly how the chemical energy released is partitioned between the fluid motion and the internal energy. A calculation is also shown for a reactive shock reflected from a rigid wall.
