Özet:

 

This paper presents Soret and Dufour effects on a 2-dimensional free  convective magnetohydrodynamic (MHD) flow of a viscous incompressible and  electrically conducting fluid through a channel bounded by a long vertical  wavy wall and a parallel flat wall. A uniform magnetic field is assumed to  be applied perpendicular to the flat wall. Governing equations of the fluid  flow and heat and mass transfer are solved analytically subject to the  relevant boundary conditions. It is assumed that the solution consists of 2  parts, a mean part and a perturbed part. The long wave approximation has  been used to obtain the solution of the perturbed part. The perturbed part  of the solution is the contribution from the waviness of the wall. The  expressions for zeroth- and first-order velocity, temperature,  concentration, skin friction, and the rate of heat and mass transfer at the  walls are obtained. Some of the results indicating the influence of Soret  and Dufour effects on the above fields are presented graphically.
