| Abstract: | In this paper, the complex flowfield induced by the interaction between the supersonic flow around the body and base jet has been numerically simulated by TVD finite volume schemes. In order to accelerate the convergence, Four-Stage Runge-Kutta time stepping method and "freezing fiscous" technique have been used, and the computational time is saved.The computed results show that the shockwave structure of interaction flowfield is very clear, which including the attached shock,intersection shock, and so on. As comparsion, the shockwave structure of free jet at the afterbody has been given. |
