| Abstract: | For one thing,the method to compute compressible reactive flow is presented in this paper,and then,using the method,a supersonic jet flow paper was computed.As the main content of the paper,the characteristic of the vortex structure was analyzed.It was found that:in the supersonic jet reactive flow,the development of the vortex structures is very different with that in the subsonic jet flow.The vortex structure affects the mixing process,through which the flame structure and the combustion efficiency is aff... |
