在短周期跨音速传热风洞上,研究不同雷诺数和压比下无气膜导叶表面换热系数分布,并在相应的数值模拟中分析叶栅通道涡结构的生成与发展,研究其对叶片换热的影响。
In the short-period transonic heat transfer wind tunnel, the distribution of heat transfer coefficients on the surface of the guide vane without gas film under different Reynolds numbers and pressure ratios was studied. The formation and development of vortex structures in cascade channels were analyzed in the corresponding numerical simulation. Effect on heat transfer of leaves.
