A Study of Nonequilibrium Effects on Ignition Delay in a Supersonic Airstream
Abstract
The purpose of the study was to determine analytically the effects of water vapor on the ignition delay process in the burning of gaseous hydrogen in a supersonic flowing vitiated airstream. A low temperature (950 - 1000K) regime was used so the reaction rates would be dominate over the diffusion rates. In the study two chemical kinetic computer programs were used to analytically predict the ignition delay times using the inputs from seven vitiated-air heater experimental investigative conditions. The analytically calculated ignition delay times, for the seven comparitive clean - air and vitiated-air cases, were then compared to the experimental results to determine the effects of water vapor on the ignition delay time.
