Numerical Study of Gas Absorption into Liquid Film on the Inside Wall of a Pipe

An improved mathematical model for. liquid film column is presented. The paper describes a theoretical analysis of the combined hydrodynamics and mass transfer effects, fur processes taking place in the liquid fihn during absorption of gas in annular. flow through a vertical pipe .Effects of liquid fihn turbulence and wavy surface were considered .In this model , we a modified Van Driest model for eddy viscosity is used. For wavy surface in annular flows Suzuki model was used. The theoretical results were compared with the experimental data, for mass transfer gas (CO.) in water (H20) and satisfactory results, were obtained.
