摘要

对已发表的有关螺旋通道内单相流及两相流关联式进行了讨论.在螺旋流内热虹吸装置内

除螺旋流(主流)外

还存在螺纹外缘与加热管内壁面缝隙间的旁流.此两流道内的流量分配可依据“流路分析法”的基本概念求解

而沸腾传热系数则按加权平均法求算.本文提出一个可供工程设计之用的计算方法.计算值与实验结果吻合良好.

Abstract

In a swirl-flow internal thermosyphon boiling device

besides the swirl-flow

a bypass stream may exist between the outer edge of the helix and the inside wall of the heated tube. The flow distribution of these two streames may be solved with the basic concepts of the streams Analysis Method and the boiling heat transfer coefficients can be calculated by means of the weighted mean method. Various published correlations of single-phase and two-phase flow in helical channels are discussed. A calculation method for engineering design is proposed. The predicted values agree with experimental results quite well.
