| Abstract: | This paper describes a numerical study of fuel air mixing process of parallel hydrogen fuel injectors that are candidates for use in scramjet combustors.Weak plane oblique shock of variant angles were used to enhance the mixing process of the fuel.The finite volume method and LU SGS implicit method along with AUSM flux splitting scheme were used to solve the 3D Navier Stokes equations.The results show great mixing efficiency enhancement of this technique. |
