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. The published related single-phase flow spiral channel and two-phase flow correlation is discussed in the spiral flow within the thermo-siphon device, in addition to the spiral flow (mainstream), there are threaded outer edge and heating pipe wall gap between the side The flow distribution in these two runners can be solved according to the basic concept of “flow path analysis method”, and the boiling heat transfer coefficient is calculated by the weighted average method.This paper presents a calculation method available for engineering design. Good agreement with the experimental results.
