摘要
The present paper deals with the magnetohydrodynamic boundary layer flow of a free convection heat transfer in an inclined square cavity filled with nanofluid-saturated porous medium. The effects of different nanoparticles Cu, Al2O3, TiO2 and SiO2 are considered. The top and bottom horizontal walls of cavity are considered adiabatic, while the vertical walls are kept at constant temperatures. The governing partial differential equations are solved by finite element method of Galerkin weighted residual scheme. Numerical results are obtained for different values of the Rayleigh number, angle of inclination, magnetic field and nanofluid volume fraction. The overall investigation of variation of streamlines, isotherms and Nusselt numbers is presented graphically. To examine the accuracy, the present results are compared with the available results.
