Natural Convection in Tilted Porous Enclosures in the Presence of a Transverse Magnetic Field
ABSTRAKT
A numerical study has been conducted on laminar natural convection heat transfer in a tilted square enclosure filled with a fluid-saturated porous medium in the presence of a transverse magnetic field. The vertical walls of the enclosure are maintained at constant temperatures while the horizontal walls are thermally insulated. The flow in the porous region is modeled using Darcy's law and the Boussinesq approximation. The control-volume finite difference method is used to solve the governing equations for different values of Darcy-Rayleigh number, Hartmann number, and inclination angle. The numerical results obtained are presented graphically in terms of streamlines and isotherms to illustrate interesting features of the solution. A new correlation for the average Nusselt number is developed in terms of Darcy-Rayleigh number and Hartmann number in vertical cavities. Typical numerical results showed excellent agreement of the present approach with the available data in the literature.
