摘　　要：利用涡速方程和一些必要的数学方法,首先建立了基于详细化学动力学的AP燃烧模型。接着在不同的入口边界条件和反应机理下,应用该模型对AP燃烧进行了数值模拟并与试验数据进行了比较。结果表明求解得到的温度场,各组分浓度场等与已有试验结果十分吻合,证实该模型可靠、精确。最后在精度方面,通过对采用不同参数模型之间的进一步比较和分析,可以看到AP燃烧的固相和凝聚相反应机理有待进一步的发展。AP combustion model with detailed chemical kinetics was established by using vorticity-velocity formulation and several essential mathematical algorithms at first. Then this model was used to simulate AP combustion at different inlet boundary conditions and chemical mechanisms. Results from the model match experimental data well, so it is proved to be accurate and reliable. At last models with different parameters are compared with each other in accuracy and it suggests that mechanisms for solid and condensed phases need improvement.
