Pulse detonation in a chamber with divergent nozzle
Detonation wave diffraction is a basic research topics of detonation dynamics and one of most important phenomena in pulse detonation engine with nozzle. Double exposure holographic interferometry, which can obtain more quantitative information compared with con- ventional visualization method such as schlieren photographic, was used to study the flow field after detonation wave. A numerical simulation based on the adaptive finite volume method with finite rate chemical reaction model was carried out to compare with the experiment result. It was found that the combination of numerical simulation with experiment can help us for better understanding of the mechanism of various phenomena accompanied with detonation diffraction process.
