Cfd Modeling Of Multiphase Counter-Current Flow In Packed Bed Reactor For Carbon Capture, Li Yang

Theses and Dissertations--Mechanical Engineering

Packed bed reactors with counter-current, gas-liquid flows have been considered to be applicable in CO₂ capture systems for post-combustion processing from fossil-fueled power production units. However, the hydrodynamics within the packing used in these reactors under counter-current flow has not been assessed to provide insight into design and operational parameters that may impact reactor and reaction efficiencies. Hence, experimental testing of a laboratory-scale spherical ball, packed bed with two-phase flow was accomplished and then a meso-scale 3D CFD model was developed to numerically simulate the conditions and outcomes of the experimental tests. Also, the hydrodynamics of two-phase flow in …
