A Comparative Study of Cantilevered Ramp Injector with Standard k-ε and RNG k-ε Turbulence Models

K.M. Pandey, Anup Baishya and Vishwa Bhushan Singh
Abstract—In this study the combustion process in a SHCRAMJET using cantilevered compression and expansion type ramp injector having 60 of both compression and expansion angle is analyzed with Standard k-ε and RNG k-ε turbulence models using FLUENT software. After designing the model in GAMBIT, it is exported to FLEUNT software for analysis of combustion process with air inlet at Mach number 7 and hydrogen as the fuel with inlet Mach number 3.5. The results obtained with both the turbulence models are compared and they explain the variations of critical parameters like temperature, pressure, density, turbulent intensity and mass fraction of H2O formed and also the extent of combustion taking place in both the cases.

Index Terms—Hypersonic combustion, ramp injector, computational fluid dynamics, turbulent intensity.
