Undulatory swimming in shear-thinning fluids: Experiments with C. elegans [PDF]

, 2014
The swimming behaviour of microorganisms can be strongly influenced by the rheology of their fluid environment. In this manuscript, we experimentally investigate the effects of shear-thinning viscosity on the swimming behaviour of an undulatory swimmer ...

Research on the influence of fluid viscosity on the inlet flow parameters of wiped film molecular distillation [PDF]

E3S Web of Conferences
Wiped film molecular distillation is a kind of evaporation device with rotating scraping film structure, which is used to separate and purify viscous materials at molecular level. The feed pump of a wiped film molecular distillation is a centrifugal pump

Dissipative hydrodynamics in 2+1 dimension

, 2006
In 2+1 dimension, we have simulated the hydrodynamic evolution of QGP fluid with dissipation due to shear viscosity. Comparison of evolution of ideal and viscous fluid, both initialised under the same conditions e.g.

Calculation of AGARD Wing 445.6 Flutter Using Navier-Stokes Aerodynamics [PDF]

, 1993
An unsteady, 3D, implicit upwind Euler/Navier-Stokes algorithm is here used to compute the flutter characteristics of Wing 445.6, the AGARD standard aeroelastic configuration for dynamic response, with a view to the discrepancy between Euler ...

Fluid Properties Effects on Sand Production using Discrete Element Method [PDF]

Journal of Chemical and Petroleum Engineering, 2018
Oil production may be accompanied by Sand Production (SP) in the weak sandstone reservoirs. Fluid flow is an important factor in transporting the separated grains and completing the SP mechanism. In this paper, the effect of fluid parameters, fluid flow,

Einstein viscosity with fluid elasticity

Physical Review Fluids, 2018
We give the first correction to the suspension viscosity due to fluid elasticity for a dilute suspension of spheres in a viscoelastic medium. Our perturbation theory is valid to $O( \mathrm{Wi}^2)$ in the Weissenberg number $\mathrm{Wi}=\dot $, where $\dot $ is the typical magnitude of the suspension velocity gradient, and $ $ is the relaxation ...

An approximate solution for a penny-shaped hydraulic fracture that accounts for fracture toughness, fluid viscosity and leak-off

Royal Society Open Science, 2016
This paper develops a closed-form approximate solution for a penny-shaped hydraulic fracture whose behaviour is determined by an interplay of three competing physical processes that are associated with fluid viscosity, fracture toughness and fluid leak ...

Viscosity, ion mobility, and the λ transition [PDF]

, 1977
A model is presented of the λ transition in superfluid helium in which fluctuations near the transition are approximated by distinct regions of normal fluid and superfluid. The macroscopic viscosity of such a medium is computed.

Bulk viscosity of the Lennard-Jones system at the triple point by dynamical Non Equilibrium Molecular Dynamics

, 2008
Non-equilibrium Molecular Dynamics (NEMD) calculations of the bulk viscosity of the triple point Lennard-Jones fluid are performed with the aim of investigating the origin of the observed disagreement between Green-Kubo estimates and previous NEMD data ...

Odd viscosity in chiral active fluids [PDF]

Nature Communications, 2017
AbstractWe study the hydrodynamics of fluids composed of self-spinning objects such as chiral grains or colloidal particles subject to torques. These chiral active fluids break both parity and time-reversal symmetries in their non-equilibrium steady states.
