In this work, we studied of variable
viscosity, Dufour and Soret effects on free
convection heat and mass transfer of a non-
Newtonian power-law fluid over a vertical full
cone in a saturated porous medium in the presence
of chemical reaction, non uniform heat
generation and thermal radiation. The transformed
nonlinear ordinary differential equations
are solved numerically using the fourthorder
Runge-Kutta method coupled with the
shooting method. The influences of various parameters
on the local Nusselt number and the
local Sherwood number are presented and discussed.
