| 英文摘要 | Scale-up of fluidized bed is a great challenge in chemical engineering. In order to explore the particle flow behavior and residence time distribution characteristics of the continuously operated polydisperse fluidized bed during the scale-up process, a large-scale parallel GPU-based coarse-grained CFD-DEM method coupled with a polydisperse and non-spherical particle drag model was used. Long-term particle residence time simulations were carried out in a continuously operated three-dimensional fluidized bed. Through the simulation of fluidized beds of different sizes (lengths), it is found that the mean residence time (MRT) of particles of different sizes has a linear relationship with the length of the fluidized bed. This relationship can be used to predict the particle MRT of larger fluidized beds. As the length of the fluidized bed increases, the difference in MRT of particles with different sizes becomes larger, indicating that the increase in the length of the fluidized bed has a certain ability to regulate the residence time of particles with different sizes. 漏 2021, Editorial Board of CIESC Journal.
