| Abstract: | The Navier-Stokes equations in the integral form are spatially discretized using finite volume method. The obtained ordinary differential equations are solved using multistage Runge-Kutta method. A three-dimensional ramjet inlet flow field is calculated. The flow field structures and surface pressure distributions of the inlet at the different backpressures are given. The interactions of shock waves and boundary layers are analyzed. |
