This paper presents computational results for mixed convective heat flow through porous medium within two entrapped trapezoidal cavities filled of kerosene-cobalt ferrofluid placed under the influence of magnetic field when heat is provided through uniformly moving top and bottom horizontal boundaries, however, the inclined walls are cold whereas middle horizontal wall is assumed insulated. Galerkin weighted residual scheme is employed to carry out the numerical results for analysis of considered flow problem. Obtained solutions are illustrated through graphs of streamlines, isotherms, local and average heat transfer rates. Results show that, the patterns of energy and fluid flow are significantly dependent upon the concentration of solid ferro particles, Grashof, Darcy and Hartman numbers.
