Mixed Convective Heat Transfer in a Rectangular Nanofluid Filled Cavity with Inclined Magnetic Field

The objective of this analysis is to discuss the effects of magnetic field and its tilted angles in a rectangular porous enclosure filled with nano fluid. The temperature at moving top wall is hot and the bottom wall remains with cold temperature, whereas the other sidewalls are adiabatic. The equations governing the considered system are solved by the finite volume method. The obtained results are discussed graphically by using isotherms, streamlines and average Nusselt number. It shows that the heat transfer rate is improved by the inclination of applied magnetic field. In the shallow cavity, the impact of Hartmann number is significant. The average Nusselt number is nearly identical when increasing Hartmann number in the slender cavity. Regardless of the permeability and the aspect ratio, enrichment in the fraction of solid and volume of nano fluid raises the overall heat transfer rate in the occurrence of magnetic field.
