| Abstract: | A model has been developed for the preparation of mass transfer by forced convection inside drops for mass transfer with and without simultaneous first-order chemical reaction. Solutions of the forced convection equation have been obtained using finite difference methods for Reynolds number and viscosity ratio ranges of 0 ≤ Re ≤ 90 and 0 ≤ μ1/μo ≤ ∞, respectively. The effect of circulation rate inside the drop on the mass transfer rate has also been studied. The model is believed to be generally applicable as evidenced by a comparison with existing analytical models. Thus the results for physical mass transfer approached the Kronig and Brink solution when the viscosity ratio tended towards zero in the Stokes' flow regime. However, as the viscosity ratio increased, the results approached the Newman solution. The model also agreed with those of Johns and Beckmann for physical mass transfer. Similarly, the results for mass transfer with first-order chemical reaction agreed with Dankwerts' generalization of the Kronig and Brink and the Newman models. |
