摘　　要：利用CFD软件CFX-TASCflow对具有试验数据的跨声速HTA涡轮导向器流场进行了计算,结果表明,计算的叶面等熵马赫数分布和出口气流角与试验值吻合良好;而计算的总压恢复系数与试验数据存在一定的差别。Three-dimensional flow fields of transonic HTA turbine stator were calculated using CFD software CFX-TASCflow.The calculated results indicate that the distributions of calculated isentropic Mach number and outlet flow angle agree well with the experimental data,however calculated total pressure recovery coeffi-cient has still some difference.
