Evaporation of water by free convection in a vertical channel including effects of wall radiative properties

The present study consists of a numerical investigation of coupled heat and mass transfers by natural convection during water evaporation in a vertica l channel heated symmetrically by a uniform flux density by taking into acc ount radiative hear transfer between the plates. The governing equations ar e solved numerically by a finite difference method. The spatial profiles of velocity, temperature and moisture are presented. The effect of ambient co nditions, channel width and walls radiation are also analysed in this study . (C) 2001 Elsevier Science Ltd. All rights reserved.
