The current study has investigated the influence of a non-uniform magnetic field on heat transfer and entropy generation through the convection flow of ferrofluid filled inside the cavity in the presence of thermal radiation.Consider that magnetohydrodynamics is the result of the applied magnetic field, induced by the Lorentz force, while ferrohydrodynamics is the effect of the Kelvin force, which is associated with the applied magnetic field that affects the magnetized liquid.The highly coupled non-linear governing system of partial differential equations are transformed sweatshirts into the set of non-linear algebraic equations by utilizing the Galerkin finite element method, and the Newton-Raphson method has been used to solve them.Results Diffuser Oil show that the fluid velocity and entropy generation are decreased via increasing Magnetic number.Intensity of streamlines decreases from 12.
407 to 1.004 by increasing Hartmann number from 0 to 5.Velocity and temperature profiles increases 31.25% and 48% respectively, by increases concentration of ferroparticles up to 0.05%.
The applications of this problem can be found in various heat transfer phenomena through fluid flow and their optimizations, such as in cooling processes of devices, advanced oxidation processes for dye removal from textile wastewater, solar collectors, chemical reactors, and heat exchangers.
