COMBINED BUOYANCY EFFECTS OF THERMAL AND MASS DIFFUSION ON LAMINAR CONVECTION IN A VERTICAL ISOTHERMAL CHANNEL

RÉSUMÉ
This paper reports on a numerical study of laminar mixed convection flow associated with mass transfer and phase change in a vertical parallel-plate channel. The plates are wetted by thin liquid water films and maintained at a constant temperature lower than that of the air entering the channel. The solution of the governing equations is based on the finite volume method with the well-known SIMPLER algorithm for handling the velocity-pressure coupling. Numerical results show that buoyancy forces have an important effect on the hydrodynamic field, as well as on the heat- and mass-transfer characteristics. These forces induce a flow reversal. Additionally, heat transfer associated with phase change (i.e., latent heat transfer) is more important compared to sensible heat transfer.
