Investigation on flow and heat transfer mechanism of corrugated internal cooling channel of turbine cascades

  • 摘要:

    针对叶片强化冷却散热的关键科学问题,提出并设计了新型波纹通道冷却结构,开展了精细化数值模拟,分析冷气进口雷诺数和波纹形状参数对其传热性能的影响,研究了高雷诺数涡轮叶片波纹通道冷却结构的流动传热机理。计算结果表明:波纹通道波峰波谷的交替出现对流场有强烈扰动效果,局部表面传热系数可达光滑通道的2~3倍;同一波纹不同位置传热效果不同,在管道收缩处表面传热系数最大;波纹通道传热能力与波纹形状密切相关,在冷气进口雷诺数较大时于H/L=0.115 附近传热效果最佳。论文揭示了波纹通道强化传热的物理机制,为航空发动机叶片冷却结构设计提供技术支撑。
