7.6.20.12.18. Krieger

Syntax

Viscosity [{of} SpeciesName] = Krieger [Beta = beta | Phi_Max = phi_max | Mu_S = mu_s | Use_Fd = use_fd]

Scope

Aria Material

Summary

A viscosity model [50] dependent on the suspension concentration $\phi$

$\mu\left(\phi\right) = \mu_s \left(1 - \frac{\phi}{\phi_{max}} \right)^{\beta},$

where $\beta$ is the Krieger exponent, $\phi_{max}$ is the maximum suspension concentration and $\mu_s$ is the solvent viscosity.
