【 摘 要 】

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