采用近似模化技术，研究了多斜孔壁的整体冷却效率。试验了五种多斜孔壁结构形式，探讨了影响整体冷却效率的各种因素。研究结果表明：多斜孔壁绝热温比、多斜孔内部对流换热以及几何结构是影响该冷却方式的关键因素。本研究对多斜孔壁冷却形式的设计和优选，尤其在几何结构参数的确定方面，具有重要意义。 Using approximate modeling technique, the overall cooling efficiency of multi-inclined hole wall was studied. Five types of multi-inclined wall structures were tested, and various factors affecting the overall cooling efficiency were discussed. The results show that the adiabatic temperature ratio, the convective heat transfer and the geometric structure in the multi-oblique hole are the key factors affecting the cooling mode. This study is of great importance to the design and optimization of the cooling form of multi-inclined hole walls, especially in the determination of geometrical parameters.
