Abstract: Experimental research is made on compound heat transfer enhancement by combination of inlet axial vane swirlers with left spirally corrugated tube,right spirally corrugated tube and symmetrical cross spirally corrugated tube,respectively.The experimental results of the tube side friction and heat transfer are given,and the corresponding friction and heat transfer dimensionless correlations which reflect the in fluence of the compound attack angle are obtained.Moreover,the thermodynamical performance curves are presented to show that given the same pump power and heat transfer area,the heat transfer rate Q of the combination in the opposite spiral direction is always higher than that of the combination in the same spiral direction,and within the experimental range,the value of Q can be increased by 90%,compared to the smooth tube．

摘要： 对进口轴向叶片旋流器与左旋螺旋槽管、右旋螺旋槽管以及对称交叉螺旋槽管组成的管内复合强化传热进行了试验研究，给出了管内阻力和传热试验结果，得到了考虑复合攻角（旋向）因素在内的管内阻力和传热准则关联式，并对传热和流阻的综合热力性能进行了定量评价．试验表明：相同泵功和换热面积条件下，旋流器与螺旋槽管反向复合后的换热量可提高至光管换热量的1．9倍．
