Shear viscosity and shear thinning in two-dimensional Yukawa liquids.
A two-dimensional Yukawa liquid is studied using two different nonequilibrium molecular dynamics simulation methods. Shear viscosity values in the limit of small shear rates are reported for a wide range of Coulomb coupling parameter and screening lengths. At high shear rates it is demonstrated that this liquid exhibits shear thinning; i.e., the viscosity eta diminishes with increasing shear ra...
متن کاملShear viscosity of two-dimensional Yukawa systems in liquid state
The shear viscosity of a two-dimensional (2D) liquid was calculated using equilibrium molecular dynamics simulations with a Yukawa potential. The shear viscosity has a minimum, at a Coulomb coupling parameter Γ of about 17, arising from the temperature dependence of the kinetic and potential contributions. Previous calculations of 2D viscosity were less extensive, and for a different potential....
متن کاملShear Viscosity of Strongly-coupled Two-dimensional Yukawa Liquids: Experiment and Modeling
This paper reviews experimental and modeling efforts aimed at the determination of the shear viscosity of strongly-coupled Yukawa liquids. After briefly reviewing prior work on three-dimensional (3D) systems, recent experimental and computer simulation studies of two-dimensional (2D) settings are presented in detail. In the experiments two counterpropagating laser beams were used to perturb a d...
متن کاملShear flows and shear viscosity in a two-dimensional Yukawa system (dusty plasma).
The shear viscosity of a two-dimensional liquid-state dusty plasma was measured experimentally. A monolayer of highly charged polymer microspheres, with a Yukawa interaction, was suspended in a plasma sheath. Two counterpropagating Ar+ laser beams pushed the particles, causing shear-induced melting of the monolayer and a shear flow in a planar Couette configuration. By fitting the particle velo...
متن کاملShear Viscosity and Diffusion in Supercooled Liquids
Under normal liquid conditions (at equilibrium or when moderately super cooled), molecular rotational and translational diffusion adhere closely to the sim ple Stokes-Einstein-Debye hydrodynamic model. Deeply supercooled "fragile" liquids present a striking exception, with translational diffusion alone occurring up to 102 — 103 times "too fast". This anomaly rests upon the statistics of fluct...
