Soret and Dufour effects on mixed convection along a vertical wavy surface in a porous medium with variable properties

(in lingua inglese)

The effects of variable viscosity and variable thermal conductivity on mixed convective heat and mass transfer past a vertical wavy surface embedded in a fluid saturated porous medium with Dufour and Soret effects have been investigated theoretically. The main conclusions of the present investigations are as follows: it is observed that increase in temperature dependent viscosity leads to thicken the velocity boundary layer while reduce the thermal and solutal boundary layer thickness as well as Nusselt number and Sherwood number.
