Turbulence models application on CFD simulation of hydrodynamics, heat and mass transfer in a structured packing

In this study, turbulence model applications on two-phase flow simulation in a structured packing are investigated using CFD application. Dry pressure drop, irrigated pressure drop, mass transfer and heat transfer are studied by k-ε, RNG k-ε, k-ω and BSL turbulence models. The best results obtained by k-ω and BSL models, but k-ω is recommended because it is more robust than BSL. The mean absolute relative error (MARE) between CFD prediction of k-ω model and experimental data for dry pressure drop, irrigated pressure drop, mass transfer and heat transfer are 16.9%, 10.7%, 8.1%, 0.9%, respectively.
