high blowing meaning in English
鼻息粗烈的
强烈吹除
Examples
- ( 2 ) on the leading edge , the film cooling effectiveness at the zone immediately downstream of the cooling holes is affected by blowing ratio and mainstream reynolds number , while the effects are not important in the downstream zone far from the cooling holes . ( 3 ) on the front half of pressure surface , the effectiveness increases with decreasing blowing ratio at the downstream near the cooling row and it is contrary at the downstream far from the cooling row . ( 4 ) on the rear pare of the pressure surface , the effectiveness decreases with increasing blowing ratio and does not vary so much downstream in the cases of higher blowing ratio
研究结果表明叶片吸力面端壁附近区域压力系数分布呈现出较强的三维特性，动叶吸力面尤其明显；气膜孔流量系数随吹风比的增加而增大，在高吹风比情况下，流量系数逐渐趋于常数；在不同型面区域，冷却效率分布有较大的差异，而且吹风比与主流雷诺数的影响程度也不尽相同；低吹风比下，孔出口下游附近可以得到较好的冷却，中、高吹风比下，冷气射流在加速流动主流的作用下返回壁面进行二次冷却，孔下游较远区域可以得到较好的冷气覆盖。
