| Summary: | Complicated interacting flow features such as shock-wave, boundary-layer and shock
induced combustion are simulated numerically in the current study to investigate the effect of the
transverse sonic fuel injection on the air-fuel mixing and flame stabilisation. The flow is
modelled using the Reynolds-averaged Navier-stocks (RANS) equations, where chemical
kinetics model is employed to compute the finite rates of chemical reactions. Turbulence is
modelled using the Baldwin-Lomax algebraic model. Finite-volume scheme is applied where the
convective fluxes are discretised by second order accurate Roe’s scheme using MUSCL
approach. Second order accurate Runge-Kutta method is used for the time-integration. Turbulent
and chemically-reacting supersonic flow of hydrogen-air mixture over a ramp is simulated and
the results show good agreement with the experimental data and the published numerical
simulations In addition, air-hydrogen flow is studied in a single strut scramjet engine, where
mixing and flame holding processes are carried out using fuel transverse sonic injection. |
