magnetohydrodynamic (MHD) flow%radial stretching%Soret and Dufour effects%porous medium%skin friction coefficient
The aim of this paper is to examine the Dufour and Soret effects on the two-dimensional magnetohydrodynamic (MHD) steady flow of an electrically conducting viscous fluid bounded by infinite sheets.An incompressible viscous fluid fills the porous space.The mathematical analysis is performed in the presence of viscous dissipation,Joule heating,and a first-order chemical reaction. With suitable transformations,the governing partial differential equations through momentum,energy,and concentration laws are transformed into ordinary differential equations. The resulting equations are solved by the homotopy analysis method (HAM).The convergence of the series solutions is ensured. The effects of the emerging parameters,the skin friction coefficient,the Nusselt number,and the Sherwood number are analyzed on the dimensionless velocities,temperature,and concentration fields.
