Turbulence Locality and Granularlike Fluid Shear Viscosity in Collisional Suspensions.
We reanalyze previous experimental measurements of solid volume fraction, mean velocity, and velocity fluctuations in collisional suspensions of plastic cylinders and water flowing over inclined, erodible beds. We show that the particle pressure scales with the granular temperature, as predicted by kinetic theory of granular gases. The assumption that the particle shear stress is also well pred...
متن کاملShear viscosity of pion gas
Shear viscosity η is one of transport coefficients in fluid dynamics, which characterizes how viscous the system is in the presence of flow gradient [1]. Since, in general, shear viscosity is inversely proportional to scattering cross-section, strongly interacting systems have smaller viscosity than weakly interacting ones. Recently a universal minimum bound for the ratio of η to entropy densit...
متن کاملDSMC evaluation of the Navier–Stokes shear viscosity of a granular fluid
A method based on the simple shear flow modified by the introduction of a deterministic non-conservative force and a stochastic process is proposed to measure the Navier–Stokes shear viscosity in a granular fluid described by the Enskog equation. The method is implemented in DSMC simulations for a wide range of values of dissipation and density. It is observed that, after a certain transient pe...
متن کاملStudy of Shear Viscosity of Amorphous Materials
Viscoelastic properties of amorphous solids deformed under uniform shear stress were studied using a kind of sandwich method with utilizing a sensitive optical technique. Time-dependent deformation data were analyzed on the basis of a mechanical model of anelasticity plus viscosity. Experiments were performed to determine the temperature dependence of viscosity for several kinds of inorganic gl...
متن کاملEffective surface-shear viscosity of an incompressible particle-laden fluid interface.
The presence of even a small amount of surfactant at the particle-laden fluid interface subjected to shear makes surface flow incompressible if the shear rate is small enough [T. M. Fischer et al., J. Fluid Mech. 558, 451 (2006)]. In the present paper the effective surface shear viscosity of a flat, low-concentration, particle-laden incompressible interface separating two immiscible fluids is c...
