Hybrid-nanofluid magneto-convective flow and porous media contribution to entropy generation

Purpose This paper aims to present a numerical study that investigates the flow of MgO-Al 2 O 3 /water hybrid nanofluid inside a porous elliptical-shaped cavity, in which we aim to examine the performance of this thermal system when exposed to a magnetic field via heat transfer features and entropy generation. Design/methodology/approach The configuration consists of the hybrid nanofluid out layered by a cold ellipse while it surrounds a non-square heated obstacle; the thermal structure is under the influence of a horizontal magnetic field. This problem is implemented in COMSOL multiphysics, which solves the related equations described by the “Darcy-Forchheimer-Brinkman” model through the finite element…
