“…Grosan et al [14] discussed the effects of the magnetic field and internal heat generation on free convection in a rectangular cavity filled with a porous medium. Thereafter, Mahapatra et al [15] studied the effects of the buoyancy ratio and thermal Rayleigh number on double diffusive natural convection in a cavity when the boundaries are uniformly and non-uniformly heated and concentrated. Later, Rahman and Sharif [16] examined the laminar natural convection in differentially heated inclined rectangular enclosures of various aspect ratios.…”
