CFD Modelling for Fluidized Bed Drying

Fluidized bed drying (FBD) is widely acknowledged to produce more considerable heat and mass transfer (HMT) and is thus acquired through several industrial drying techniques, mostly farming goods. This chapter reviewed recent advances in FBD, focusing on the drying associated with Computational Fluid Dynamics (CFD) utilization. Using modern computational techniques such as CFD assists in optimizing the FBD operation and design for more negligible energy utilization and, thus, better thermal efficacy. The agricultural goods studied in this chapter include oil palm fronds, olive, coconut, wheat grains, peppercorn, and millet. Mathematical modeling of FBD is vital for optimizing the execution of present systems and the design of novel dryers. In CFD modeling, the drag force between solids and gas phases is the most significant parameter to predict the fluidized bed‘s flow features. Drying is the most essential operation unit in producing solid pharmaceuticals. The fluidized bed (FB) is utilized for particle distribution (PD) amid 40–500 μm. The additional benefit of employing FBD at the industrial level is the high HMT and mixing in the bed. FBD can reduce the drying period to various minutes rather than the numerous hours traditional dryers need.
