cone shaped hole

To investigate the influence of the hole shape on the film cooling effectiveness of the maze composition structure of a combustor,a numerical study on the distribution of its wall temperature and cooling effectiveness was performed when the outside wall holes were dust-pan shaped holes,cone shaped holes and round holes.

为了获得开孔形状对燃烧室新型迷宫复合冷却结构冷却效率的影响规律,采用数值模拟方法研究迷宫冷却结构的外侧壁冷却孔分别为簸箕形孔、圆锥形孔和圆柱形孔时内外壁温的分布情况,获得其壁温及冷却效率的分布规律,并在迷宫冷却结构三层壁的热侧面对它们的冷却效率进行对比。

Experiments on dust pan shaped holes, cone shaped holes and round holes have been conducted with secondary flow Reynolds number ranging from 10,000 to 25,000 and blowing ratio ranging from 0.

所用孔形是簸箕形孔、圆锥形孔及圆柱形孔 ,实验的参数范围为二次流孔径雷诺数 Re=1 0 0 0 0～ 2 5 0 0 0 ,二次流吹风比 M=0 。
