A Comparative Study of Hybrid-Nanofluid’s Behavior Filled with a Square Enclosure Considering the Effect of Hartmann Number

Abstract

This article exposes the behavior of hybrid nano-fluid flows and temperature comprising pure water as base fluid along with Al2O3-Cu and Ag-TiO2 nanoparticles in a square enclosure with the presence of magnetic field parameter. The cavity was considered as top and bottom half of side walls are cooled whereas the rest walls are thermally insulated. Governing equations of the current study have been converted into a system of the non-linear ordinary differential equations and then are solved numerically by utilizing Finite Element technique to investigate the effect of pertinent parameters. Numerous values of Hartmann number Ha=0-100 and Rayleigh number Ra=103- 105 have been examined, while a Prandtl number Pr=6.26 has been used through-out the numerical simulation. Findings are shown in graphical form to identify the variations in velocity and temperature profile for two different considered cases of hybrid nanofluids. It was observed that the magnetic field has a significant impact on the fluid flow and temperature distribution. Also, it was found that the Rayleigh number plays a vital role on both streamlines and isotherms.
