Abstract

As one of the most successful modifications to conventional fluidized beds to intensify their operations, vibrated gas-fluidized beds (VGFBs) have been used extensively in industry. Here, we review the hydrodynamics within VGFBs and their applications to improve fluidization quality of particles that are difficult to fluidize based on gas flow alone, to control segregation and mixing among different particle types, and to enhance heat and mass transfer. Further, recent progress in creating structured flow patterns in VGFBs to facilitate the scale-up of fluidized beds and development of methods for numerical modeling of vibration in VGFBs are discussed. Finally, perspectives on the areas for future work on VGFBs are given.

振动气体流化床研究进展

振动气体流化床作为对传统流化床进行强化处理的一种最成功的改造方法，在工业上得到了广泛的应用。本文综述了流化床内流体力学的研究进展及其在改善单靠气流难以流化的颗粒的流化质量、控制不同颗粒类型之间的分离和混合以及增强传热传质等方面的应用。此外，本文还讨论了在VGFBs中创建结构化流动模式以促进流化床放大的最新进展，以及VGFBs中振动数值模拟方法的发展。最后，对未来研究的方向进行了展望。

期刊介绍： Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published. The goals of each review article in Current Opinion in Chemical Engineering are: 1. To acquaint the reader/researcher with the most important recent papers in the given topic. 2. To provide the reader with the views/opinions of the expert in each topic. The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts. Themed sections: Each review will focus on particular aspects of one of the following themed sections of chemical engineering: 1. Nanotechnology 2. Energy and environmental engineering 3. Biotechnology and bioprocess engineering 4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery) 5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.) 6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials). 7. Process systems engineering 8. Reaction engineering and catalysis.
