Heat Transfer and Entropy Generation in Vibrational Flow: Newtonian vs. Inelastic Non-Newtonian Fluid [PDF]
Journal of Applied Fluid MechanicsA computational method is employed to solve heat transfer and entropy generation within a circular pipe. The thermal boundary condition assumes a constant wall temperature, while viscosity is taken to be dependent on temperature.

Theory of nonlinear rheology and yielding of dense colloidal suspensions
, 2002 A first principles approach to the nonlinear flow of dense suspensions is presented which captures shear thinning of colloidal fluids and dynamical yielding of colloidal glasses. The advection of density fluctuations plays a central role, suppressing the

Pipe flow of shear-thinning fluids Pipe flow of shear-thinning fluids
, 2012 Lʼécoulement de fluides rhéofluidifiants en conduite cylindrique est étudié à lʼaide de simulations numériques. Le comportement rhéofluidifiant est modélisé par la loi de Carreau. Lʼécoulement est décomposé en un écoulement de base et une perturbation.

Shear thinning in deeply supercooled melts [PDF]
Proceedings of the National Academy of Sciences, 2009 We compute, on a molecular basis, the viscosity of a deeply supercooled liquid at high shear rates. The viscosity is shown to decrease at growing shear rates, owing to an increase in the structural relaxation rate as caused by the shear. The onset of this non-Newtonian behavior is predicted to occur universally at a shear rate significantly lower than ...

Applications in Engineering ScienceThe stability of steady, fully developed flow in a long cylindrical pipe for a shear-thinning fluid (which approximates a class of viscoplastic materials) is studied using linear stability analysis. The eigenvalues of the frequency of the perturbation of

Polymer Optimisation- Shear Thinning or Thickening?
Asian Journal of Applied Sciences, 2019 With most polymers employed in polymer enhanced oil recovery exhibiting one or both non-Newtonian behaviours that is shear thickening and thinning at different shear rate, it is expedient to analyse the impact of these non-Newtonian behaviours in polymer optimisation.

Shear thickening in concentrated suspensions: phenomenology, mechanisms, and relations to jamming
, 2013 Shear thickening is a type of non-Newtonian behavior in which the stress required to shear a fluid increases faster than linearly with shear rate. Many concentrated suspensions of particles exhibit an especially dramatic version, known as Discontinuous ...

Dip coating of shear-thinning particulate suspensions
Soft MatterDip coating a planar substrate with a suspension of particles in a shear-thinning liquid will entrain particles in the liquid film, facilitating filtration and sorting of particles.
