One-Dimensional Modeling of Hydrodynamics in a Swirling Fluidized Bed

The present work studies the hydrodynamics of a swirling fluidized bed (SFB) for packed and swirling regimes using an analytical model that draws inspiration from the order-of-magnitude analysis approach. In minimizing the complexity in solving the hydrodynamics model in SFB, the multiple-dimensiona...
