Firstly, for jet array impingement cooling, the effects of the distance of adjacent holes, the impinging distance and jet reynolds number on heat transfer characteristic at the target wall are summarized under staggered holes arrangement and the same hole diameter. and then, the numerical simulation of inclined multi - hole film cooling has been studied. the influence factors examined in this case include blowing ratio and the distance of adjacent holes
首先通過對射流沖擊冷卻方式的研究,分析了相鄰孔間距、沖擊間距以及射流入口雷諾數對沖擊靶面換熱系數的影響情況,然後對多斜孔冷卻方式進行了數值模擬,重點探討了吹風比和相鄰孔間距對絕熱溫比與壁面換熱系數的影響規律,最後,針對沖擊-發散復合冷卻流場的計算物理模型,研究吹風比、相鄰孔間距的變化對沖擊-發散復合冷卻流動與傳熱特性的影響。 -
