A computational study using Large Eddy Simulations to investigate combustion dynamics in an ethylene-hydrogen-air ramjet test rig. The flame in the current set-up changes its anchoring point between a jet-wake stabilized and a cavity-stabilized position. The highly dynamic combustion behaviour is investigated numerically and compared against previously published experimental data.
