The thesis introduces a CFD framework for deflagration-to-detonation transition (DDT) risk assessment in stratified H2-CO-air mixtures. Validated against small- and large-scale experiments, it handles fully- and semi-confined geometries. The CFD simulation considers geometrical and reactive dependencies of DDT, resulting in a more generally applicable DDT risk analysis strategy for combustion-related accidents than empirical criteria. The solver features a load-balancing algorithm for large-scale simulations, reducing computation time significantly.
