| 摘 要： | 提出了壳程轴流型换热器的优化目标函数，分析了最优化条件的存在性，并对三种矩形排列的光滑管、缩放管以及花瓣管的优化程度进行了传热性能的研究，与所得实验结果进行了对比，两者结论一致。研究表明：对于相同排列的三种管子，花瓣管的目标函数最小，缩放管次之，光滑管最差；对于同一种管子，22mm×28mm排列最优，22mm×26mm排列次之，22m×m24mm排列最差.

| Abstract: | An optimal objective function for shell and tube heat exchanger with axial-flow shell side was presented and optimal conditions were analyzed.The optimum magnitude of three rectangular pitches of bare tubes,convergent and divergent tubes and petal-shaped fin tubes was studied in respect of heat transfer performance. The conclusions obtained correspond well with experiment results.The results of study show that, for three types of tubes of same pitch,the objective function of petal-shaped fin tube is the sma... |
