摘　　要：分析了微转子发动机的燃烧特点,在双区准维模型的基础上引入壁面熄火区,提出了三区准维模型。编制了适用于微转子发动机燃烧的计算程序,计算了三区准维模型和双区准维模型下的微转子发动机燃烧过程。通过对计算结果与U.C.Berkeley试验数据比较分析,说明了三区准维模型的合理性。After analyzing the combustion characteristic of the mini Wankel-type rotary engine, appending a new flam-out zone based on the double-zone quasi dimension model,this paper brought forward threezone quasi dimension model used for the combustion process simulation of the mini rotary engine,While fuel gas was H2 ＋Air, the simulation results of the two models were compared with the experiment data of U.C. Berkeley. The results show that the calculation by the three-zone quasi dimension model is more reasonable than that by the double-zone quasi dimension model.
