A Numerical Analysis on MHD Mixed Convective Hybrid Nanofluid Flow Inside Enclosure with Heat Sources

Abstract

The MHD mixed convection inside a lid driven enclosure having heat sources filled with hybrid nanofluid is investigated numerically. This study aims to analyze the impact of Richardson number (0.01 ≤ Ri ≤ 100), Hartmann number (0 ≤ Ha ≤ 100) and different combination of hybrid nanoparticles (Ag–MgO, Ag–TiO2 and Ag–CuO) on fluid flow and heat transfer inside the enclosure. The finite volume method was used to solve the governing equations. The values of Ri, Ha, Re were found to have a great influence on thermal transport of hybrid nanofluids concerned in this investigation. Furthermore, at Ri = 100, the heat transfer rate is maximum for all values of Hartmann number. Increasing values of Richardson number strongly enhances the heat transfer rate whereas Hartmann number attenuates the aggrandization of heat transfer. It has been concluded that the rate of heat transfer of Ag–CuO/water hybrid nanofluid is higher than Ag–TiO2/water and Ag–MgO/water.
