本文在ＫＩＶＡ－Ⅱ程序中实现了由作者提出的一个新的相关火焰模型。该模型的火焰面积密度的毁灭项中，从分形几何的角度出发引入了湍流的作用。通过对工质为丙烷的火花点火发动机进行的变工况计算，对新模型与Ｂｏｕｄｉｅｒ的燃烧模型进行了对比。结果表明，新模型合理地考虑了湍流的作用，计算结果与实验值吻合更好。 In this paper, a new related flame model proposed by the author is implemented in KIVA-Ⅱ program. In the destruction of the flame area density of the model, turbulence is introduced from the perspective of fractal geometry. Comparing the combustion model of Boudier with the new model, the spark loss of propane was calculated by changing the working conditions. The results show that the new model reasonably considers the effect of turbulence, and the calculated results are in good agreement with the experimental ones.
