本文提出一类新型的动态旋转列管式设备,对旋转管束两侧流体的传热和传质机理进行了分析讨论。通过动态旋转技术,可以有效抑制管束间流体的沟流效应,同时管内流体将出现类似Dean游涡的二次流,从而使得管两侧的传递效果都将得到改善。最后展望了这种设备在膜组件、超重力机等方面的应用前景。
Abstract：The concept of rotating tube bundle in process engineering is brought forward,and the heat and mass transfer process concerned on both sides of the rotating tube bundle are analysed.Through the proposed technique, channelling effect is reduced on the shell side of rotating tube bundle, a secondary flow similar to Dean vortices do exist in a rotating tube, and the heat and mass transfer efficiencies on the shell side are improved.Anticipation of some applications,such as rotating tubular and/or hollow fiber membrane,rotating packed bed with tube bundle,are surveyed.
