摘要
在二维柱坐标下,基于详细化学动力学,利用涡速方程和有限差分方法,对AP气相燃烧进行了数值模拟。数值模拟采用了29个组分和79个有限化学反应方程,较真实地体现了AP气相燃烧的实际过程。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。
Based on 2-D cylindrical system, AP gas-phase combustion model with detailed chemical kinetics was established by using vorticity-velocity formulation and finite difference method. This model includes 29 species and 79 reactions,representing real AP combustion process. Results obtained from the model agree well with those from the experiments which proves that the model is reliable and accurate.
