Heat and Mass Transfer at the Film-Gas Interface

Abstract

There are different flow patterns leading to a film/gas interface in multiphase flows. Stratified and annular flows in channels with different geometry, walls of large pools with different orientations and part of the stratified liquid gas configuration in large pools are the flow patterns of practical interest. The problem of the mathematical modeling of interface heat and mass transfer consists of (a) macroscopic predictions of the geometrical sizes and local averaged temperatures, velocities, concentrations and pressure and (b) microscopic modeling of the interface heat and mass transfer. The purpose of this chapter is to review the state-of-the-art for modeling of the interface heat and mass transfer for known geometry.
