本文从传热强化、摩擦系数强化和强化效率三个方面讨论了螺旋强化管的性能，并将其作为单一无量纲几何参数的函数，即严重性。60多个不同管道的传热和摩擦系数数据显示，当绘制为严重程度的函数时，会塌陷为一条分散性最小的曲线。结果表明，在湍流中，摩擦系数的增加通常比相应的传热增加大得多。 此外，严重程度在0.001和0.01之间的值显示，可产生湍流的最佳增强。单位:双引文:研讨会，ASHRAE交易，1988年，第94卷，pt。2、渥太华

The performance of spirally enhanced tubes is discussed in this paper in terms of heat transfer enhancement, friction factor enhancement, and enhancement efficiency as a function of a single nondimensional geometric parameter, the severity. Heat transfer and friction factor data from more than 60 different tubes are shown to collapse to a single curve with minimal scatter when plotted as a function of the severity. It is shown that in turbulent flow the increase in friction factor is usually much larger than the corresponding increase in heat transfer. In addition, values of severity between 0.001 and 0.01 are shown to yield optimum enhancement for turbulent flow.Units: Dual
