Investigation of Turbulent Mixing and Local Reaction Rates on Deflagration to Detonation Transition in Methane-Oxygen

Abstract

drive transverse pressure waves outward. Upon subsequent shock reflections or interactions of the transverse waves, new local explosion events occurred, which further strengthened the adjacent leading shock wave above the CJdetonation speed. Eventually, through this process, the wave sustained the CJ-detonation speed, on average, through the cyclic mechanism of local explosion events followed by turbulent surface reactions. Finally, combustion of the flame acceleration process was found to lie predominantly within the thin-reaction zones regime.
