On the evolutions of induction zone structure in wedge-stabilized oblique detonation with water mist flows

Two-dimensional wedge-stabilized oblique detonations in stoichiometric and fuel-lean H2/O2/Ar mixtures with water mists are studied using Eulerian-Lagrangian method. The effects of droplet mass flow rate on chemical structures the induction zone, as well physical / roles vapor, investigated. results show that detonation wave (ODW) can stand a range rates for both mixtures. With increased rate, deflagration front zone is distorted becomes zigzagged, but transition mode from shock (OSW) to ODW does not change. Moreover, initiation locations monotonically increase, OSW angles decrease, due evaporation vapor dilution region. For mixtures, sensitivity characteristic loading variations mild, which signifies better intrinsic stability resilience oncoming droplets. explosiveness gaseous mixture between lead reaction explosive analysis. smooth caused by highly enhanced reactivity gas immediately behind curved shock, intensified compression waves. Nonetheless, abrupt intersection beforehand generated OSW. Beside, degree reduced evaporating droplets generally lower than gas. Also, liquid result significant differences morphology. When occurs, influence location angle, only one important transition.
