THE EFFECT OF RECOMBINATION RATE ON THE FLOW OF A DISSOCIATING DIATOMIC GAS

Abstract

The flow of a chemically reacting gas through a divergent nozzle is considered. A pure diatomic gas is assumed to dissociate and recombine according to seven distinct recombination rate laws. The effect of correcting Lighthill's ideal dissociating gas for vibrational contributions of the molecular species and translational contributions of the atomic species is shown to be small. The effect of recombination rate on the flow of oxygen, from throat conditions of 2 atm and 4050 K, is shown to be significant for reaction rates decreasing with temperature and relatively unimportant for reaction rates increasing with temperature. Electronic analog computer solutions are presented for a variety of throat compositions and recombination rates.
