Numerical Analysis of Magnetic Field Effect on Ferro Particle Suspended Nanofluid Filled Square Enclosure Consist of Heat Generating Body

Abstract

In presents of a magnetic field, an enclosure filled with ferro-particle suspended nanofluid is subjected to a numerical analysis to investigate natural convective heat transfer. At the center of the enclosure is a heat conducting and generating solid body, and the enclosure is influenced by four different thermal boundary conditions. To solve the governing equation, a Fortran algorithm based on the finite volume approach was created. The numerical approach used in this study produces consistent results for a variety of non-dimensional parameters like Rayleigh number (104 ≤ Ra ≤ 106), Hartmann number (0 ≤ Ha ≤ 100), solid volume fraction (0 ≤ φ ≤ 0.2) and distributed wall temperature. Streamlines, isotherms, and the Nusselt number graph are used to describe the flow and heat transfer properties. Based on this study, It has been noted that improved heat transfer for lower Hartmann number with higher Rayleigh number particularly along sinusoidal wall. For the low Hartmann number, the fluid flow enhances for higher Rayleigh number. In particular, the presence of ferro-particle suspended nanofluid enhances the heat transfer rate. Moreover, this study has found that the inclusion of magnetic fields and nanoparticles can increase heat transfer by up to 60%. The suggested methods in this research can assist manufacturers improve efficiency without increasing heat generator space in industrial applications for cooling or heating.
