| 摘 要： | 研究了多斜孔壁冷却方式小孔内对流的局部和平均换热情况。研究方法是相似理论指导下的实验研究。研究结果表明：小孔进口区的换热增强幅度较大，并且在进口区不同的位置上增幅存在差别；孔内雷诺数对换热增强幅度影响较大，孔内雷诺数越高，换热增强越大。

| Abstract: | The local and the overall convective heat transfers inside the small holes have been investigated experimentally for the inclined multihole wall film cooling,according to the similarity theory.The results demonstrate that the convective heat transfer intensifies very greatly in the region inside the hole entrance.The results also reveal that the Renolds number of the hole has strong influence on the convective heat transfer.The higher the Renolds number,the more intensive the convective heat transfer inside the hole. |
