本文阐述了在一台涡旋流动传热试验装置上所进行的不同旋流强度的空气介质在环形套管内涡旋流动特性和传热特性的试验研究，探索涡旋流强化传热的机理及效果。得到该形式涡旋流换热系数和旋流数的关系，并和相同条件下无涡旋流动的换热数据比较，结果表明涡旋对换热效果的影响很大。该研究结果可为新型的涡旋热交换器提供设计参考依据。 In this paper, the experimental study on the vortex flow and heat transfer characteristics of the air medium with different swirling intensities carried out on a vortex flow heat transfer test device in an annular casing was discussed. effect. The relationship between the heat transfer coefficient and the swirl number is obtained and compared with the heat transfer data without swirling flow under the same conditions. The results show that the swirl has a great influence on the heat transfer effect. The results of this study provide a reference for the design of a new type of scroll heat exchanger.
