In this study, the unstart phenomenon in a scramjet engine triggered by fuel injection was numerically simulated using an in-house code. The analysis domain was set to encompass an intake, isolator, and combustion chamber of a scramjet engine. Flow characteristics within the scramjet’s internal flow duct were investigated as the fuel injection increased until unstart occurred. To simulate the dynamic flow characteristics within these internal flow duct, the KW-SST based Hybrid RANS/LES method was applied, incorporating compressibility correction and low Reynolds number correction. Based on the analysis results, the unstart was detected using the CUSUM algorithm. Additionally, the position of the shock train leading edge was quantified by implementing the Pressure Rise Ratio.
