Effect of Inclination Angle and Magnetic Field on Convection Heat Transfer for Nanofluid in a Porous Cavity

In this paper, the effect of inclination angle and magnetic field in a two-dimensional porous cavity filled with Cu-water nanofluid has been studied numerically. The equations are framed using the Darcy-Brinkman-Forchheimer model. The control volume technique is used to solve the governing equations and SIMPLE algorithm is employed for the momentum equations. Comparison test was done with previous available literatures and the results are found to be in good agreement. The results are presented for different values of inclination angle (۰ o g ۱۸۰ o ), Hartmann number (۰ Ha ۱۰۰), Darcy number (۱۰ ۵ Da ۱۰ ۱ ) and solid volume fraction (۰% ۵%) while the porosity e, Rayleigh number Ra and Prandtl number Pr are fixed at ۰.۶, ۱۰ ۶ and ۶.۲, respectively. It is found that the influence of solid volume fraction is strongly affected by the presence of strong magnetic field and the inclination angle ۹۰ o in the porous medium.
