研究了具有不同扭曲比的全长螺旋元件和不同垫片长度的螺旋插入物的水平扁管双层管内的传热特性和摩擦系数。管程和壳程分别采用冷水和热水作为工质。实验涵盖了雷诺数5.7 x 10（2）的范围
The heat transfer a characteristics and friction factor in the horizontal double pipes of flat tubes with full length helical screw element of different twist ratio and helical screw inserts with different spacer length are investigated. Cold and hot water are used as working fluid in tube side and shell side respectively. The experiments covered a range of Reynolds numbers 5.7 x 10(2)
