Numerical simulation for external magnetic field influence on Fe₃O₄-water nanofluid forced convection

Purpose The purpose of this paper is to simulate nanofluid laminar steady flow in a lid-driven porous cavity under the impact of Lorentz forces. Design/methodology/approach Shape effect of nanoparticles and magnetic field impact on nanofluid properties are taken into consideration. The solutions of final equations are obtained by control volume based finite element method (CVFEM). Findings Graphs are depicted for different values of Darcy number, Fe 3 O 4 -water volume fraction, Reynolds and Hartmann numbers. Originality/value Results illustrated that using Platelet-shaped nanoparticles results in the highest Nusselt number. Nusselt number augments with rise of Darcy and Reynolds number.
