Fully developed mixed convection flow of a nanofluid through an inclined channel filled with a porous medium

摘要

In this paper, the steady fully developed mixed convection flow of a nanofluid in a channel filled with a porous medium is presented. The walls of the channel are heated by a uniform heat flux and a constant flow rate is considered through the channel. The equations of the problem are made non-dimensional and are observed to depend on the dimensionless parameters, namely the mixed convection parameter λ, the Peclet number Pe, the inclination angle of the channel to the horizontal λ and the nanoparticle volume fraction φ. The effects of these parameters on the fluid and heat transfer characteristics are in detail discussed for three different nanofluids as Cu-water, Al_2O_3-water and TiO_2-water.
