  • Abstract

    Steady laminar mixed convection and MHD effect inside a double lid-driven oblique cavity filled with a ferrofluid is studied numerically using the finite element method. An isothermal heater is placed on the left inclined wall of the cavity while the right wall is maintained at a constant cold temperature. The horizontal top a bottom moving walls are kept adiabatic. The oblique cavity is filled with a mixture of kerosene-cobalt ferrofluids. The numerical computations are obtained for various parametric values of the inclination angle of the sloping walls, Hartmann number and the volume fraction of the ferromagnetic particles. It is shown that the transfer rate is clearly enhanced with the augmentation of the ferromagnetic particles volume fraction under the influence of a relative magnetic field.
