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

Nusselt number scaling in tokamak plasma turbulence [PDF]
Physics of Plasmas, 2005 Anomalous heat transport caused by ion temperature gradient (ITG) driven turbulence in tokamak plasmas is evaluated from numerical simulations of the two-dimensional (2D) partial-differential equations of the ITG model and of a reduced 1D version derived from a quasilinear approximation.

Numerical investigation of nanofluid flow and heat transfer over a backward-facing step
Engineering and Applied Science Research, 2020 In this research, the forced convection heat transfer of a nanofluid in a channel with a backward- facing step is studied by adopting the finite volume technique. The effect of nanoparticles is considered by employing the single-phase model.
