The grooves on the heated surface lowered the flow resistance and enhanced the film heat transfer coefficient 2-3 times that of flat plates.
相同雷诺数的槽板平均表面换热系数是平板的2～3倍，同时减小了流动阻力。
Thermal resistance is reduced and heat transfer is enhanced by surface repeated ribs in rib -roughened tubes. The tubes will be applied in packaging equipment broadly.
肋粗糙管通过表面粗糙减小了热阻，促进了传热。该粗糙管在包装设备上将会得到广泛的应用。
Enhanced surface was used in heat transfer equipment widely, and the surface condition has an important influence on the fouling process.
强化传热表面在工业换热设备中具有广泛应用，其表面状况对于传热与结垢过程均有重要影响。
