Numerical Simulation of Forced Heat Convection Turbulent Magnetic Nanofluid Flow in a Square Channel

Abstract:

This paper presents numerical study of turbulent nanofluid (Fe₃O₄ - water) flow in a square straight channel. An ANSYS FLUENT commercial software was employed to investigate the flow and thermal characteristic of the flow in the range of Reynolds number 10,000 to 50,000 and nanoparticle volume concentration from 0% to 2%. The results show that by increasing the Reynolds number, the Nusselt number increased for both pure water and nanofluid cases. The thermal conductivity and viscosity of the nanofluid were increased with an increase in the particle volume concentration and yields enhancement of heat transfer.
