摘要
文中对管内强化传热及复合强化传热技术进行了在紊流流动下的阻力和传热特性分析，并给出了几种复合强化传热技术的试验研究结果，提出螺旋槽管中插入旋向相反的部分管长扭带是行之有效、效果明显的复合强化传热技术。
With respet to in tube intensified heat transfer and combination intensified heat transfer technology presented in this paper is an analysis of resistance and heat transfer characteristics under turbulent flow conditions.Experimental research results of several kinds of combination intensified heat transfer techniques are also given.It is pointed out that the insertion of a partial tube length twisted tape with a counter rotation in a spiral corrugated tube can be regarded as a highly effective combination intensified heat transfer technique.
