Nusselt Number and Convection Heat Transfer Coefficient for a Coaxial Heat Exchanger Using Al2O3-Water pH=5 Nanofluid [PDF]

open access: yesBulletin of the Polytechnic Institute of Jassy: Constructions, Architechture Section, 2009
Recently, a new class of fluid made up of metal nano-particles in suspension in a liquid, called nanofluid, appeared. Some numerical studies have shown that these new fluids have a higher heat transfer performance, compared with the conventional liquids.
