Cross¶
A Cross Fluid is a generalized non-Newtonian fluid with an effective viscosity, \(\mu_{\operatorname{eff}}\) , defined by:
\[\nu_{\operatorname{eff}}(\dot \gamma) = \nu_{\operatorname{\infty}} + \frac{\nu_0 - \nu_{\operatorname{\infty}}}{1+\left(K \dot{\gamma}\right)^N }\]
where \(\nu_{\operatorname{\infty}}\) is the viscosity at infinite shear, \(\nu_0\) is the viscosity at zero shear, \(N\) is the power index, and \(K\) is a shear rate coefficient.

Fluid Properties
¶
- Rheology Type
Apply Cross rheology. Local fluid viscosity is calculated from the local shear rate using a user-defined rate constant, time constant, and infinite/zero share rate viscosities.
- Density
kg/m 3 | The density of the fluid.
- Cross V0
m 2 /s | Viscosity at zero shear.
- Cross Vinf
m 2 /s | Viscosity at infinite shear.
- Cross N
Rate constant.
- Cross K
s | Time constant.
