Abstract
The objective of this paper is to investigate the combined heat and mass transfer process near a vertical wavy semiinfinite surface embedded in a doubly stratified electrically conducting fluid-saturated Darcy porous medium under the influence of Soret and Dufour effects. The governing coupled non-dimensional partial differential equations are transformed to boundary layer equations using the two point local non-similarity transformation which is obtained by scale analysis. The resulting boundary layer equations are solved numerically by applying the Keller Box finite difference scheme. The heat and mass transfer has been analysed by plotting the Local, Average Nusselt and Sherwood numbers for various values of parameters influencing the model like: Mg (Magnetic field effect), a (amplitude of wavy surface), ST and SC (Thermal and Mass Stratification), Sr (Soret number), Df (Dufour number), Buoyancy ratio (B), Lewis number (Le).
