摘要
利用风洞实验 ,研究了Re =1× 10 4～ 1× 10 5范围内滴形钉头管在不同攻角下的流阻特性 .实验结果表明 ,攻角对滴形钉头管的流阻特性影响显著 ,流阻最小值出现在攻角α为 180°时 ,最大值出现在攻角α为10 0°～ 110°时 .还给出了不同攻角下Eu与Re之间的关联式 .
The experimental research of the hydraulic resistance within Re =1×10 4～1×10 5 is carried out for the pin finned drop shaped tube at different attack angles by means of the wind tunnel .The results show that the attack angle dramatically affects the hydraulic resistance. The lowest hydraulic resistance is at the attack angle of 180°, and the highest hydraulic resistance is between the attack angle of 100°～110°. The experimental results are generalized by correlations between Eu and Re .
