Abstract
A model for combined mass and heat transfer during nonisothermal absorption of a one component gas in a Vertical gas-liquid slug flow with liquid plug s containing small bubbles is suggested. Under the assumptions of a perfect mixing of the dissolved gas in liquid plugs and uniform temperature distri bution in liquid plugs, recurrent relations for the dissolved gas concentra tion and temperature in the nth liquid plug and mass and heat fluxes from t he nth unit cell of a gas-liquid slug flow are derived. The total mass and heat fluxes in a gas-liquid slug flow are determined. Theoretical results a re compared with the available experimental data. (C) 1998 Elsevier Science Ltd. All rights reserved.
