| 摘 要： | 通过三维CFD数值模拟软件ANSYS-CFX模拟优化4种波纹板式换热器,计算区域为1-1程的三流道板式换热器包括进出口段和倒流区段。数值计算结果表明,Φ=60°的新型板式换热器比Φ=60°的人字形板式换热器的努塞尔数高约15%,摩擦阻力系数低约10%,综合性能提高约20%,其中波纹比例系数为3∶1的板片的综合性能最优。

| Abstract: | Four kinds of corrugated plate heat exchangers(PHE) were simulated applying three-dimensional CFD software——ANSYS-CFX.Three-flows plate heat exchanger whose computational domain is 1-1 process,includes import and export segment and reflux section.The results from numerical simulations show that Nusselt number of the working fluid in new-type PHE with Φ=60°,compared with the chevron-type one,is increased by 15%,the flow resistance is decreased by 10%,and the performance evaluation criteria is increased by 20%.The plate with corrugation ratio of 3∶1 is better than any other type. |
