Morphology of oblique detonation waves in a stoichiometric hydrogen–air mixture
Journal of Fluid Mechanics, 2021Although the morphology of oblique detonation waves (ODWs) has been widely studied, it remains impossible to predict the wave systems in the initiation region, which is a critical component in promoting engine applications.
