摘要

横纹管是70年代中期出现的一种高效换热元件.它加工简单

制造成本低廉

可在泵功率消耗不增加的情况下

显著地强化管内流体的传热效果.因此

在化工、石油化工、动力及海水淡化等行业中引起了广泛的重视并越来越多地应用于工业.

Abstract

The friction and heat transfer tests of 16 different structural parameter (e/d= 0.022-0.058; t/e=9.09-36.36) of transversally corrugated tubes were made with water as working medium

Reynolds number 5000-50000. The fluid flow patterns were observed by using several transparent models of hydrogen bubble flow tracers. The general correlations for friction factor and Stanton number were obtained with a semi-theoretical and semi-statistical method. Prediction of Fanning friction factor and Stanton number were given with the errors within ±12% as compared with experimental data.A transversally corrugated tube of optimal structural parameters was obtained under certain operation condition. The heat transfer performance of transversally corrugated tube was superior to the spiral grooved tube recommended by previous studies.
