ON THE INTERACTION BETWEEN CHEMICAL KINETICS AND GAS-DYNAMICS IN THE FLOW BEHIND A CYLINDRICAL DETONATION FRONT

Abstract

The interaction of chemical kinetics and heat release phenomena with the gasdynamics of the flow appreciably alters temperature, density, and flow velocity behind the incident shock wave. This in turn influences the strength and decay rate of the shock at later times. The detonation cell geometry and spacing are thus dependent upon the nonsteady kinetic rate processes in the shocked gas. Overall effects of the chemical processes for the H2-O2 system are strongly influenced by initial pressure and, to a lesser degree, gas composition.
