A numerical analysis of nonequilibrium flow of a reacting gas mixture in a supersonic nozzle
Abstract
Nonequilibrium one-dimensional flow of a reacting gas mixture consisting of an oxidizer (air, nitrogen oxide, or ozone) and a fuel (hydrogen + carbon monoxide) in a supersonic flow is investigated numerically. It is assumed that the carbon dioxide molecule is formed during the reaction in the electron-excited a3 Pi state. Two hypothetic mechanisms of the relaxation of the CO2 molecule to the ground state followed by vibrational energy exchange with other mixture components are examined.
