Cross fluid

From Wikipedia, the free encyclopedia

A Cross fluid is a type of generalized Newtonian fluid whose viscosity depends upon shear rate according to the following equation:

$\mu_{\operatorname{eff}}(\dot \gamma) = \frac {\mu_0}{1 + ({\frac {\mu_0 \dot \gamma} {\tau ^ *}})^{1-n} }$

where

$\mu_{\operatorname{eff}}(\dot \gamma)$ is viscosity as a function of shear rate,

μ 0

,

τ *

and n are coefficients.

At low shear rate ( $\mu_0 \dot \gamma \ll \tau^*$ ), cross fluids behave as Newtonian fluids and at high shear rate ( $\mu_0 \dot \gamma \gg \tau^*$ ) as power-law fluids.
