NONSIMILAR HYDROMAGNETIC SIMULTANEOUS HEAT AND MASS TRANSFER BY MIXED CONVECTION FROM A VERTICAL PLATE EMBEDDED IN A UNIFORM POROUS MEDIUM.

This work considers steady, laminar, hydromagnetic simultaneous heat and mass transfer by mixed convection flow over a permeable vertical plate immersed in a uniform porous medium for the cases of power law variations of both the wall temperature and concentration and the wall heat flux and mass flux. Appropriate transformations are employed to transform the governing differential equations to a nonsimilar form. The transformed equations are solved numerically by an accurate, implicit, iterative, finite difference method. The obtained results are validated by favorable comparisons with previously published work on special cases of the problem. A parametric study illustrating the influence of all involved parameters on the local Nusselt and Sherwood numbers is conducted. The results of this parametric study are shown graphically, and the physical aspects of the problem are discussed. [ABSTRACT FROM AUTHOR]
