叶片外部换热实验和数值研究

摘要

The heat transfer distribution of a vane without film hole was studied in a short du-ration transonic heat transfer wind tunnel at differ-ent Reynolds numbers and pressure ratios,and the generation and development of flow vortex struc-ture in cascade passage were numerically analyzed to study its effect on the heat transfer.%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。
