用非正交曲线坐标系数值计算航空发动机加力燃烧室无化学反应的湍流流场

COMPUTATION OF TURBULENT FLOW IN A AFTERBURNER WITHOUT REACTION UNDER GENERALIZED NONORTHOGONAL CURVILINEAR COORDINATE SYSTEMS

本文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无化学反应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．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．加力燃烧室湍流流场数值计算结果合理．

In this paper the non-reacting turbulent flow in a afterburner with tIiree stabilizers arecalculated using the SIMPLE method under curvilinear coordinate with nonstaggered gridsystem. The turbulence model is k-E model. Grid generation is zonal method. Computationis conducted on all zones until the iteration convergence is arrived. The results are reasonable.
