The implementation of a strut injection scramjet combustor with double ramps is numerically investigated employing Reynolds Averaged Navier Stokes (RANS) equations and the Shear Stress Transport (SST) k- \(\omega\) turbulence model. The key parameters like shock wave formation, static pressure distribution, and temperature distribution through the combustor are studied to analyze the impact of the position of ramps on the efficacy of the scramjet combustor. The numerical shadowgraph reveals significant shock reflections in double ramp scenarios, potentially reducing downstream flow velocity. The scramjet combustor with ramps achieves complete combustion in a 20% shorter combustor length while increasing pressure loss across the combustor by 5% compared to the DLR model. The ramp positioning within the combustor provides a marginal variation in its performance.
