Possibility of Dissociation Reactions Occurring in Polyatomic Molecules during Rapid Cooling in an Expanding Supersonic Flow

Abstract

Studied is the possibility of the occurrence of the dissociation reaction of N2O and the exchange reaction of N2O+CO to N2+CO2 in rapid cooling of a gas mixture as a result of supersonic expansion in a nozzle. Balance equation for vibrational energy and the kinetics of the chemical reaction under nonequilibrium conditions are solved numerically. The values of parameters necessary for experimental observations of the studied phenomenon are found.
