摘　　要：对空气斜向冲刷圆管束时的管外传热系数与流动阻力进行了实验研究 ,并对实验结果作了分析 ,给出了实验条件下的传热与流阻关联式 ,为斜向冲刷圆管束设计提供了数据依据 .实验结果表明 ,斜向冲刷圆管束比横向冲刷时具有更好的综合传热效果 .Experiments of heat transfer coefficient and flow resistance of air flowing obliquely across round tube bundles have been investigated in this paper. The experimental data have been correlated and the correlation results are presented, which can provide the design data for air flowing obliquely across tube bundles. The experiments indicate that better integrated performance of heat transfer enhancement can be obtained by air flowing obliquely across round tube bundles than by vertically across them.
