Experimental investigation of forced convection heat transfer and friction factor of a non-Newtonian nanofluid flow through an annulus in the presence of magnetic field
In this current work, the forced convection heat transfer and pressure drop of a non-Newtonian nanofluid flow through an annulus are studied experimentally. The steady-state laminar flow of the nanofluid takes place in the presence of a constant heat flux and a constant magnetic field. The non-Newto...

| description | In this current work, the forced convection heat transfer and pressure drop of a non-Newtonian nanofluid flow through an annulus are studied experimentally. The steady-state laminar flow of the nanofluid takes place in the presence of a constant heat flux and a constant magnetic field. The non-Newtonian nanofluid used is carboxymethyl cellulose (CMC)/copper oxide solution with 0.2% CMC weight fraction and 0.25, 0.5 and 1% volume fractions of copper oxide nanoparticles in the distilled water. Based on the experimental results obtained, the heat transfer coefficient augmented as the volume fraction of the nanoparticles was increased. Also, it was found that the presence of the magnetic field enhanced the heat transfer effectively. Based on the results, the mean Nusselt number for 1 vol% was increased by 16.49% compared to that of the base fluid. |
