| 摘 要： | 对涡与扩散火焰的相互作用是涡轮喷气发动机燃烧室中十分重要的问题.本研究通过数值计算揭示了在对涡形成的流场中扩散火焰的结构以及扩散火焰对流场的影响.当不考虑释热引起密度变化时,数值解与相应的解析解符合较好.

| Abstract: | The interaction of diffusion flame with vortex pair is essential for understanding of combustion. The structure of diffusion flame in flow fields with vortex pair and the effect of the diffusion flame on the flow fields are discussed in the paper.The numerical results show excellent agreement with the analytical solution to flame structure when the effect of heat release due to chemical reaction and the change of density are not to be considered. |
