In this paper, the mass transfer from Taylor bubble in circular capillaries was simulated by a VOF based mass transfer model. In this model the mass transfer in both gas and liquid is considered and this method is suitable for flows with mass transfer resistance in both phases. The accuracy of presented mass transfer model was investigated both analytically and experimentally. The results show that the developed model supplies an adequate basis for investigation of mass transfer process in gas–liquid multiphase system.<\div>

In this work the effect of capillary number variation on dynamic mass transfer from Taylor bubble in monolith reactors has been investigated by CFD techniques. The Volume Of Fluid (VOF) based interface tracking method in conjunction with a mass transfer model was used. The values of mass transfercoefficient (kLa) has been calculated for different capillary numbers. CFD simulation shows that by increasing the capillary number the recirculating vortex and liquid velocity near the bubble caps becomes smaller. At higher capillary number also the longer bubble and the thicker liquid film appear around the bubble. The results show that by increasing the capillary number the different mass transfer mechanismshas been taken place for Taylor bubble flow through the monolith reactor.<\div>
