摘要

本文提出一种多头与单头螺旋槽管管内单相流体对流传热准数方程的关联法

对普兰特数Pr从0.7到35的三种介质——空气、水及甘油与水的混合物进行了管内传热准数方程的关联

其关联形式较简单

关联效果良好

适用于工程计算

也有助于传热理沦的研究.

Abstract

A method in proposed for correlating heat transfer coefficient in spiral-fluted tubes upon analysis of the distribution of heat transfer resistance. A correlation for turbulent single-phase flow is thus obtained

Valid for both single-and multiple-start spiral-fluted tubles

are a wide range of Prandtl number (Pr = 0.7 to 35).
