摘要：

Computational fluid dynamics is used to investigate the mass transfer from the liquid phase to the channel wall for Taylor flow of bubbles rising in circular capillaries. The separate influences of the Taylor bubble rise velocity, unit cell length, gas holdup, and liquid diffusivity on mass transfer were investigated for capillaries of 1.5, 2 and 3 turn diameter. A correlation is proposed for estimation of the wall mass transfer coefficient and this correlation has been tested against published experimental data. (C) 2004 Elsevier Ltd. All rights reserved.
