Numerical Studies of Multiphase Flow in Structured Packings

A volume of fluid multiphase flow model was used to investigate effective area and created liquid film in the structured packings. The computational results showed that the gas and liquid flow rates play significant roles on the effective interfacial area of the packing. In particular, the effective area increases as the flow rates of both phases increase. Numerical results were compared with the Brunazzi model, and a goodagreement was found. Attention was given to the process of liquid film formation in both 2D and 3D models. Current study revealed that CFD can be used as an effective tool to provide information on the details of gas and liquid flows in complex packing geometries.
