New computational approach for exergy and entropy analysis of nanofluid under the impact of Lorentz force through a porous media

摘要

In current simulation, role of magnetic forces on ferrofluid second law treatment via innovative computational method has been reported. To estimate behavior of porous media, Non-Darcy model has been involved. Contours display the impact of magnetic force, Rayleigh and Darcy numbers. Iron oxide is considered as nanoparticles which are dispersed in to water. Results exhibit that exergy drop detracts with reduce of magnetic force. Bejan number detracts with decrease of permeability. As buoyancy forces improve, S-gen,S-th enhances. (C) 2018 Elsevier B.V. All rights reserved.
