Experimental investigation of forced convection heat transfer and friction factor in a tube with Fe3O4 magnetic nanofluid

Abstract The nanofluid used was a stable colloidal suspension of magnetite (Fe 3 O 4 ) nanoparticles of average diameter 36 nm. The convective heat transfer coefficient and friction factor characteristics of Fe 3 O 4 nanofluid for flow in a circular tube is evaluated experimentally in the range of 3000  φ
