NUMERICAL STUDY OF HEAT AND MASS-TRANSFER FROM AN INCLINED FLAT-PLATE WITH WET AND DRY ZONES

This paper presents a theoretical study of momentum, heat and mass transfer in the laminar boundary layer which develops over an inclined flat plate by either free or forced convection when a constant wall heat flux is specified: this plate is made with two wet zones which are separated by a dry one. From the theoretical analysis, a set of dimensionless coupled equations is deduced and numerically solved by using an implicit finite difference method. The results show the effect of most of the main physical quantities upon velocity, temperature and concentration profiles in the boundary layer: from this study, the length of the dry separation zone appears as an essential criterion.
