Abstract/Summary Three-dimensional, non-reacting, computational fluid dynamics simulations of an elliptical scramjet combustor with cavity flameholder are presented. The injection and mixing of gaseous methane and hydrogen fuels are examined. A one dimensionalised inflow boundary condition, computed from full flowpath simulations of a Mach 8 shape-transitioning scramjet inlet, is used. Fuel mass flow rates were chosen to match experiments performed in the T4 Reflected Shock Tunnel, and result in equivalence ratios of approximately 0.6. The simulations show the effect that fuel injection upstream of the cavity has in a three dimensional geometry. Further to this, hydrogen penetrates further into the core flow of the combustor compared to methane, but this results in reduced entrainment in the cavity.
