摘要
通过三维N-S方程,对某型燃气涡轮起动机涡轮级和喷管内部的三维流场进行了数值模拟计算,分析了通道内的涡系产生和流动分离,揭示了该涡轮级和喷管内部流场的物理特征,为该起动机的改进设计提供了理论依据,并为整机的数值模拟奠定了基础。
3D N - S codes are used for numerical simulation of the flow field in turbine stages and nozzle of a gas turbine starter. Vortices formation and flow separation in the flow passage are analyzed, and the flow field physical characteristics in the turbine stage and nozzle are summarized. The results provide theoretical references for the design improvement, and lay the foundation to numerically simulate the full - scale gas turbine starter.
