Cell model of nonisothermal gas absorption in gas-liquid bubbly media.

Author(s) : ELPERIN T., FOMINYKH A.

Summary

A model for combined mass and heat transfer during nonisothermal gas absorption in a two-phase gas-liquid bubbly medium with a high gas content and/or large times of gas-liquid contact is suggested. Diffusion and thermal interactions between bubbles is taken into account. Distribution of concentration of dissolved gas, temperature distribution in liquid and coefficients of mass and heat transfer during nonisothermal absorption of a soluble pure gas from a bubble by liquid are determined. In the limiting case of absorption without heat release the derived formulas recover the expressions for isothermal absorption.
