CFD modeling of turbulent forced convective heat transfer and friction factor in a tube for Fe3O4 magnetic nanofluid in the presence of a magnetic field

Computational fluid dynamics (CFD) tool is used to study numerically a nanofluid mixture of water and Fe3O4 with MHD effect. The simulation is performed in order to determine the turbulence forced convection heat transfer in a circular tube. This is implemented by using the single and two phase mixture approaches with assumption that the particles are spherical and diameter equal to 36 nm. The simulation output data compared with an experimental literature data from other study and found matching. The result shows that Nu and friction factor at fixed Reynolds number is proportional to the magnetic field. (C) 2017 Taiwan Institute of Chemical Engineers. Published by Elsevier B.V.
