摘要

对多种结构的横纹管管内速度场和温度场进行了数值模拟

按场协同原理分析了其中3种横纹管管内湍流换热情况。考虑不同管型的流动阻力差异

对其换热能力进行了综合评价比较

从而得出最佳管型。分析结果表明:在入口流速为0.5~3 m/s的范围内

最佳管型的综合换热能力是常用横纹管的1.3倍左右。

Abstract

The velocity field and temperature field in transversally corrugated tubes of different structure have been numerically simulated

according to the field synergetic principle

the terbulent heat transfer in three kinds of these transversally corrugated tubes has been analysed.Considering the difference of flow resistance is different type of said tubes

the heat transfer ability of said tube types has been comprehensively evaluated and compared

therefrom

the best tube type being obtained.Results of analysis show that the comprehensive heat transfer ability of the best tube type is up to about 1.3 times of that in commonly used transversally corrugated tubes under condition of inlet flow velocity being in a range of 0.5~3 m/s.
