Closures for simulation of gas-liquid flows in solid foam structures

Subramanian, K.; Baldota, R.; Schubert, M.; Lucas, D.; Hampel, U.

Ceramic foam packings are promising alternatives for packing internals used in chemical engineering processes due to their high porosity and high specific surface area, which results in low pressure drop and high catalytically utilization of the packing. The aim of this work is to perform three-dimensional Computational Fluid Dynamics (CFD) simulations of the evolving gas-liquid flow patterns considering ceramic foams as column internals and to validate them with experimental X-ray tomographic studies. The closures from trickle bed studies are modified according to the ceramic foam specifications considering the flow domain as porous.

Keywords: Multiphase flow; CFD; Ceramic foams; X-ray tomography
