Shear viscosity of a crosslinked polymer melt
– We investigate the static shear viscosity on the sol side of the vulcanization transition within a minimal mesoscopic model for the Rouse-dynamics of a randomly crosslinked melt of phantom polymers. We derive an exact relation between the viscosity and the resistances measured in a corresponding random resistor network. This enables us to calculate the viscosity exactly for an ensemble of cro...
متن کاملMicro-Viscometer for Measuring Shear-Varying Blood Viscosity over a Wide-Ranging Shear Rate
In this study, a micro-viscometer is developed for measuring shear-varying blood viscosity over a wide-ranging shear rate. The micro-viscometer consists of 10 microfluidic channel arrays, each of which has a different micro-channel width. The proposed design enables the retrieval of 10 different shear rates from a single flow rate, thereby enabling the measurement of shear-varying blood viscosi...

متن کاملShear 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 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...
