| Abstract: | In this paper,the third order ENN scheme is used to solve the complete Navier Stokes equations for the supersonic flow over oblique detonation ram accelerator.The numerical results show that the present third order scheme can capature the shock wave,expansion wave and detonation wave clearly.Furthmore,it also has high resolution for viscous separation flowfield calculation.Meanwhile,the mechanism of acceleration is clarified by the numerical simulation,and the code for calculating the thrust and flowfield about ram accelerator is also given. |
