Basic Instability Mechanisms in Chemically Reacting Subsonic and Supersonic Flows.
Abstract
This report summarizes the main results and conclusions obtained in a research program on basic instability mechanisms in chemically reacting flows. Both theoretical and experimental work was conducted to determine the linear and the non-linear coupling between chemical kinetics and gas dynamics, which lead to wave interactions necessary for sustaining the instabilities. Acoustic, chemical and mixed modes of instability were identified. Non-linear wave-kinetic coupling was found to be important at high activation energies for weak shocks. Threshold values of shock strength and pulse width are required to initiate detonations or explosions. (Author)
