Simulation of a full-scale oblique detonation engine configuration running on hydrogen-air
Simulation of a full-scale oblique detonation engine configuration running on hydrogen-air
In this study, external injection ODWE experiments are simulated using AMROC (Adaptive Mesh Refinement in Object-oriented C++), our block-structured, adaptive mesh refinement framework for the simulation of shock-induced combustion phenomena. Mid-plane simulations are conducted using a two-dimensional domain with accurate embedded boundaries to create the geometry of the inlet ramp, combustor, and nozzle. The external injection system and mixing process are simplified to a perfectly mixed fuel-air stream with a known freestream Mach number, temperature, and pressure. Comparisons between numerical and experimental results are made using measured combustor wall pressures, oblique shockwave (OSW) angles, and detonation wave angles. Here, we provide all setup details that have allowed us to achieve CFD validation for the prototype ODWE configuration experimentally investigated by Zhang et al. at the Chinese Academy of Sciences.

Abstract
In this study, external injection ODWE experiments are simulated using AMROC (Adaptive Mesh Refinement in Object-oriented C++), our block-structured, adaptive mesh refinement framework for the simulation of shock-induced combustion phenomena. Mid-plane simulations are conducted using a two-dimensional domain with accurate embedded boundaries to create the geometry of the inlet ramp, combustor, and nozzle. The external injection system and mixing process are simplified to a perfectly mixed fuel-air stream with a known freestream Mach number, temperature, and pressure. Comparisons between numerical and experimental results are made using measured combustor wall pressures, oblique shockwave (OSW) angles, and detonation wave angles. Here, we provide all setup details that have allowed us to achieve CFD validation for the prototype ODWE configuration experimentally investigated by Zhang et al. at the Chinese Academy of Sciences.
