Shock Wave - Boundary Layer Interaction in Reactive H2/O2 Mixture

摘要

This work shows that in a smooth tube filed with a reactive mixture shock waves produced by a propagating flame are the cause for an autoignition in the boundary layer. Fluid dynamic interaction and induction time play the most important role. The new flame that develops from the autoignition is recognized as a fast flame becasue it travels faster than the local speed of sound.
