Vapor Absorption into Liquid Films Flowing over a Column of Cooled Horizontal Tubes


Department of Mechanical Engineering,Sharif University of Technology


In this paper, a theoretical analysis of the combined heat and mass transfer over cooled horizontal tubes is presented. The boundary layer assumptions are used for the transport of mass, momentum and energy equations and the finite difference method is employed to solve the governing equations in the absorber tube bundle. The effects of important parameters, such as solution flow rate absorber pressure and tube radius, are discussed on the overall heat and mass transfer for a tube and tube bundle.
