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.

振动气体流化床的进展

作为对传统流化床强化操作最成功的改造之一，振动气体流化床（VGFB）已在工业中得到广泛应用。在这里，我们回顾了 VGFB 内的流体动力学及其应用，以提高仅基于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，并增强传热和传质。此外，还讨论了在 VGFB 中创建结构化流动模式以促进流化床规模扩大和 VGFB 振动数值模拟方法开发的最新进展。最后，给出了 VGFB 未来工作领域的展望。
