Experiment of cooling effectiveness with double-outlet film hole

  • 摘要: 为了进一步理解双出口气膜孔的冷却特性,建立了气膜冷却效率实验台,通过红外测温技术研究了圆孔和4个不同次孔方位角的双出口孔在吹风比为0.3~2.0时的冷却效率.结果表明:和圆孔相比,次孔方位角为30°,45°,60°双出口孔能提高面平均冷却效率18%~37%.次孔方位角为30°双出口孔在低吹风比下提高冷却效率最显著,次孔方位角为60°双出口孔在高吹风比下提高冷却效率最显著.在研究的吹风比范围内,次孔方位角为45°双出口孔都能较显著地提高冷却效率,次孔方位角为75°双出口孔冷却效率低于圆孔冷却效率.
