Nusselt number correlations for heat transfer analysis around a tube at subcritical Reynolds numbers [PDF]

open access: yes, 2021
Nusselt number around circular tube has been typically correlated by the power law: Nu= C Rem Prn. In the present study, a numerical technique of Matrix least-squares has been utilized to estimate coefficient and power indices of the typical power law ...

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.
