中文摘要：

研究了具有尾缘槽缝和多排复杂冷气喷射进口弯掠导叶的气膜冷却特性，所研究的叶片具体有2个冷却腔，尾缘劈缝与副冷却腔相连，表面总共布置有11排冷气喷射孔，给出了多孔气膜冷却叶片几何构造和网格生成的过程。给出了不同湍流度下叶片中部区域叶片型线上的压力系数和速度比分布情况，并讨论了各个位置上的分布特点。探讨了在内表面换热和外表面气膜覆盖条件下，压力面和吸力面上展向的平均实际气膜冷却效率沿流向的分布特点，并且对各自冷却特点进行了分析。

英文摘要：

This paper studied film cooling effectiveness of certain guide vane which constitute of tail slot and multi-rows of cooling holes structure. The vane has two cooling cavities which second cavity communicate with tail slot. There are eleven rows of cooling holes lay on the vane surface. The paper demonstrated the process of solid modeling and mesh generation. The Cp and Cu located at middle of vane was presented and the character of corresponding location was discussed. The mean lateral film cooling effectiveness on pressure side and suction side along streamwise direction was reported under inner surface heat conduction and outer face film cooling condition, the trait of both surface was analyzed.
