跨声速涡轮叶栅三维流场的数值模拟

Numerical simulation of the three-dimensional flow field of transonic turbine cascade

以具有试验测量数据的一个高压涡轮动叶中截面平面叶栅和一个高压涡轮导向器环形叶栅为对象,采用计算流体动力学(CFD)软件CFX-TASCflow,对两个涡轮叶栅的跨声速三维粘性流场进行了数值计算,验证了CFX-TASCflow软件在航空燃气涡轮设计计算中的可靠性,并对所研究的跨声速涡轮叶栅粘性流场进行了分析.

A three-dimensional Navier-Stokes simulation was performed numerically for a transonic turbine planar cascade and a transonic turbine annular cascade using CFD software CFX-TASCflow code. The results show that CFX-TASCflow code software could predict reliably turbine cascade flow field and its performance. The characteristics of the researched transonic turbine cascades viscous flow field were analyzed.
