In this study, three-dimensional CFD analysis was carried out for a hydrogen fueled scramjet engine tested at the Ramjet Engine Test Facility (RJTF) under Mach 6 flight conditions. As a result, for a fuel equivalence ratio of 0.3, various combustion modes were observed depending on the combustor wall temperature, operation of igniter, presence of water vapor in air conditions as well as initial solutions. Those combustion modes were classified into 4 groups: Partially-anchored, Fully-anchored, Partially-blow-off and Blow-off modes, from the point of view of flame anchor point, and were investigated in detail. In addition, it was demonstrated that several combustion phenomena occurred in the RJTF tests corresponded to one of them.
