empirical model parameter
\ln {\mu}_{12} = \frac{x_1}{x_1 + \alpha \, x_2} \cdot \ln {\mu}_1 + \frac{\alpha \, x_2}{x_1 + \alpha \,x_2} \cdot \ln {\mu}_2 |
where
| dynamic viscosity of fluid mixture | dynamic viscosity of the 1st fluid component | dynamic viscosity of the 2nd fluid component | |||
empirical model parameter | mole fraction of the 1st fluid component | mole fraction of the 2nd fluid component |
The empirical parameter can be fitted to lab data.
For it reduces to Arrhenius equation.
