Effects of Meshing Type and Turbulency Model on Flow Distribution of Gas/Liquid Two Phase Systems of Structured Packing Employing CFD Technique

The effects of meshing type and turbulency model on distribution and volume fraction of the liquid phase on the MontzpakB1-250Y structured packing at steady state condition was investigated employing computational fluid dynamics (CFD) technique. The volume of fluid method was used to simulate the liquid distribution, while different meshing types (e.g. tetrahedron and cooper algorithm) and turbulency models (including Standard, RNG and Realizable) were used for modelling the system. Resulted equations were numerically solved employing the finite volume method. Liquid maldistribution was studied using parameter and volume fraction of the liquid phase at various velocities and conditions. The results were compared with experimental data reported in the literature indicating that a proper selection of meshing type and turbulency model can significantly affect hydrodynamics simulation of the structured packing.
