| Abstract: | A mathematical model of natural convection to non-Newtonian fluids inside porous media in a clcaed cylindical cavity is presented. Theoretical and nunierical analysis reveals Darcy-Rayleigh number and rheological exponent effects on flow fields aI1d temperature distributions,as well as,rheo-logical behaviour,Nusselt numbers changing law versus any Rayleigh number and rheological exponent is analysed. |
