采用非正交曲线坐标系下非交错网格的ＳＩＭＰＬＥ方法，对航空发动机加力燃烧室气相燃烧的湍流流场进行了数值计算，湍流模型采用ｋ－ε双方程模型，平均化学反应速率采用涡旋破碎模型（ＥＢＵ）计算，对ＥＢＵ模型的缺陷作了讨论。差分网格采用分区方法生成，计算时对整个流场进行分区迭代直至得到收敛结果，数值计算结果合理。
Using non-staggered grid SIMPLE method in non-orthogonal curvilinear coordinate system, the turbulent flow field of aero-engine afterburner combustion was numerically calculated. The k-ε two-equation model was adopted for the turbulent model. The average chemical reaction rate Spin broken model (EBU) calculations, the defects of the EBU model are discussed. The differential grid is generated by the partition method. During the calculation, the whole flow field is partitioned and iterated until the convergence result is obtained, and the numerical calculation result is reasonable.
