Heat Generation/Absorption Effect on Natural Convection Heat Transfer in a Square Enclosure Filled with a Ethylene Glycol - Copper Nanofluid Under Magnetic Field
This paper examines the natural convection in a square enclosure that is filled with a nanofluid. This nanofluid with Ethylene Glycol based containing Copper nanoparticle is influenced by a uniform horizontal magnetic field and uniform heat generation or heat absorption. The enclosure is bounded by two isothermal vertical walls at different temperatures and by two horizontal adiabatic walls. The governing equations needed to deal this problem (mass, momentum, and energy) are solved numerically using the commercial simulation software COMSOL Multiphysics. In order to increase the natural convective heat transfer in a square cavity, the effect of heat generation or absorption on the isothermal, streamline contours and the Nusselt number are studied when the Prandtl number is Pr = 151.
