摘要

采用短周期冷态传热风洞研究了某型放大动叶表面静压及换热系数分布

实验中雷诺数和叶栅压比范围涵盖了叶片的典型工作状态。结果表明:压比是影响表面压力系数的主要因素

雷诺数的影响可以忽略; 雷诺数和压比都会影响表面换热系数和绝热壁温

随着雷诺数的增大

叶片表面换热系数增加

吸力面转捩点前移

大雷诺数的换热系数分布趋势有别于小雷诺数; 保持主流总温不变

随着叶栅压比的增大或雷诺数的减小

绝热壁温降低

小雷诺数下绝热壁温实验值低于平板的理论计算值。

Abstract

Surface pressure and heat transfer measurements for an enlarged blade were conducted in a short-duration cold heat transfer wind tunnel at representative Reynolds numbers and pressure ratios. The results suggest that the blade pressure ratio is the main factor affecting the pressure coefficient distribution

while the effect of the Reynolds number can be neglected. The Reynolds number and pressure ratio both contribute to the heat transfer coefficient and local adiabatic wall temperature. With the increase in Reynolds numbers

the surface heat transfer coefficients increase and the transition point of the suction side moves upward

showing that the heat transfer coefficients distribution at larger Reynolds numbers is different from that at smaller Reynolds numbers. The local adiabatic wall temperature decreases with an increase in the pressure ratio or the decrease in the Reynolds number at constant main stream total temperature. Additionally

the experiment data for the local adiabatic wall temperature are smaller than the analytical solution for flat plates at small Reynolds numbers.
