Risk analysis of potential accident scenarios involving flame acceleration and deflagration-to-detonation transition (DDT) is a central aspect in chemical and process engineering. The large variety of process conditions does not allow for comprehensive experimental investigations. Therefore, a hybrid pressure/density-based solver is presented, which is capable of simulating deflagrative flame acceleration as well as DDT and detonation. The solver uses under-resolved grids in combination with a reaction progress variable approach.
