twoLiquidMixingFoam viscosity of the mixture

Dear Foamers,

How is the viscosity of the mixture calculated in twoLiquidMixingFoam ?
Where is it defined ?

After searching the OF Forum I found some speculations, that the viscosity of the mixture is calculated linearly.
What seems to be incorrect form the physics point of view because viscosity do not add linearly.

Thanks,
ZMM

Hi, Did you find the answer to your question?

Where are density and viscosity equations defined?
