“…The results show that the heat transfer performance of the three-dimensional tube is better than that of the smooth tube after Xiuzhen Li et al [3][4][5], who studied the heat transfer performance of a three-dimensional tube bundle with lateral air scour. Based on the analysis of the comprehensive heat transfer performance and the law of the three-dimensional tube used in the shell and tube heat exchanger and flue gas heat exchanger by Xun Mo et al [6][7][8], it is concluded that the comprehensive performance of the three-dimensional tube is the best among several kinds of enhanced tubes. Lei Yang et al [9] studied the comprehensive performance of the three-dimensional tube using water and steam as the heat exchange medium, and found that the three-dimensional tube with low water flow rate has obvious advantages.…”

The three-dimensional tubular heat exchanger has excellent performance in single-phase flow, but its performance in gas solid two-phase flow is still lacking research. In this paper, analysis and comparison of heat exchanger prototypes made up of four different three-dimensional tubes by different comprehensive performance evaluation methods are carried out through experimental research and theoretical analysis. The research results show that the ratio of the long axis to the short axis of the three-dimensional tube has an important influence on its heat transfer performance and flow resistance. Furthermore, a reasonable ratio can be obtained by comparing its comprehensive performance. Among the comprehensive performance analysis results of four kinds of three-dimensional tubes, the comprehensive performance factor ηo-I of type I is the best which achieves the purpose of heat transfer enhancement. Results from the current research could provide beneficial guidance for further design and application of the three-dimensional tubular heat exchanger.
