Title: Analysis of Applicability of Navier-Stokes Equation for Dusty Plasma Liquid Viscosity Investigation

Abstract

It was for the first time when viscous properties of dusty plasma liquid was experimentally investigated along with the dependencies of them on background pressure and the value of shear tension applied to the liquid. The viscosity of dusty plasma liquid was found to increase with background gas pressure and decrease with external tension. It is hypothesized that the non-newtonian behaviour of dusty plasma liquid is explained by small attraction between macroparticles. Also the semi empirical criterion of Navier-Stocks equation applicability for dusty plasma liquid description.

    The technique of combining solutions of the Prandtl equations with solutions of the Navier--Stokes equations to compute incompressible flow around two-dimensional bodies is investigated herein. Computational evidence is presented which shows that if the obvious'' coupling is used to combine the solutions, then the resulting solution is not accurate. An alternate coupling procedure is described which greatly improves the accuracy of the solutions obtained with the combined equation approach. An alternate coupling that can be used to create a more accurate vortex sheet/vortex blob method is then shown.

    The near zone energy-momentum tensor of a supersonic heavy quark jet moving through a strongly coupled N=4 super Yang-Mills (SYM) plasma is analyzed in terms of first-order Navier-Stokes hydrodynamics. It is shown that the hydrodynamic description of the near quark region worsens with increasing quark velocities. For realistic quark velocities, v=0.99, the nonhydrodynamic region is located at a narrow band surrounding the quark with a width of approximately 3/{pi}T in the direction parallel to the quark's motion and with a length of roughly 10/{pi}T in the perpendicular direction. Our results can be interpreted as an indication of the presence ofmore » coherent Yang-Mills fields where deviation from hydrodynamics is at its maximum. In the region where hydrodynamics does provide a good description of the system's dynamics, the flow velocity is so small that all the nonlinear terms can be dropped. Our results, which are compatible with the thermalization timescales extracted from elliptic flow measurements, suggest that if anti-de-Sitter/conformal field theory (AdS/CFT) provides a good description of the BNL Relativistic Heavy Ion Collider system, the bulk of the quenched jet energy has more than enough time to locally thermalize and become encoded in the collective flow. The resulting flow pattern close to the quark, however, is shown to be considerably different from the superposition of Mach cones and diffusion wakes observed at large distances.« less

    We present the results of our experimental study of the flow of a dusty plasma liquid produced by macroparticles in an argon plasma. The dependences of shear viscosity for such a liquid on the magnitude of the external force inducing the dusty plasma liquid flow and on the plasma-generating gas pressure are analyzed. We have established that the viscosity of a dusty plasma medium decreases with increasing shear stress in it, while the viscosity of such a liquid increases with buffer gas pressure. The flow of a dusty plasma liquid under the action of an external force has been foundmore » to resemble the plastic deformation of a Bingham body. We suggest that the formation of crystal-like dusty plasma clusters in a 'liquid' phase can be responsible for the non-Newtonian behavior of the dusty plasma liquid flow.« less
