| Abstract: | On the basis of 3-D viscous, turbulent and reactive Navier-Stokes numerical equation, the finite-rate chemistry/eddy-dissipation model for modeling the turbulent combusion is established. The fluid dynamic mechanisms of the dual-mode scramjet combustor using hydrogen as the fuel is studied. The effects of the ratio of the air to fuel, fuel injection angle and flight Mach number on the dual-scramjet working mode are analyzed, and the function of the isolator is analyzed too. |
