Experimental study of nonequilibrium dissociation of molecular oxygen

Abstract

The quantitative experimental data on the evolution of gas temperature (T ) and vibrational temperature (T v ) of molecular oxygen behind the strong shock wave front (T = 4,000 10,800 K) were used for determination of oxygen vibrational relaxation time and dissociation rate constants under thermal nonequilibrium conditions. Some of theoretical models of thermal nonequilibrium dissociation were tested using the measured pro¦les of the T v and T .

Simulation of Relaxation Processes in Hypersonic Flows with One-Temperature Non-Equilibrium Model

“…With distance from the shock wave front, this influence becomes insignificant [29]. The processes of vibrational relaxation and thermally non-equilibrium dissociation of oxygen are discussed in [30].…”
