Parametric Study of Experimental and CFD Simulation Based Hydrodynamics and Mass Transfer of Rotating Packed Bed: A Review

Abstract The emission of CO 2 into the atmosphere is one major causes greenhouse effect, which has a devastating effect on environment and human health. Therefore, reduction in high concentration essential. Rotating Packed Bed (RPB) reactor gained lot attention post-combustion capture due to its excellent rate mass transfer efficiency. To better understand mechanisms underlying process ensure optimal design RPB for absorption, elucidating hydrodynamics paramount importance. Experimental investigations have been made past study using advanced imaging instrumental setups such as sensors actuators. employments instruments are still challenging difficulties their installation placement owing complex engineering RPB. can be affected by various operational parameters. However, all them cannot evaluated single setup. experimental generally result partial understanding flow behavior cons pros methods reported critically discussed this paper. Computational Fluid Dynamics (CFD), other hand, powerful tool visually insights with accurate prediction. Moreover, different multiphase turbulence models employed also reviewed in-depth along advantages disadvantages each model. Sliding Mesh Model (SMM) rotating reference frame model adopted investigating current research gaps future recommendations presented paper contribute fill existing gap CFD analysis absorption.
