I am trying to run nonNewtonianIcoFoam with transportProperties being powerLaw.
I have a flow curve of non-Newtonian flud. I found the thread on transportProperties for powerLaw ************************************ transportModel powerLaw; nu nu [0 2 -1 0 0 0 0] 1e-05; powerLawCoeffs { k k [0 2 -1 0 0 0 0] 2500; n n [0 0 0 0 0 0 0] 0.4; nuMin nuMin [0 2 -1 0 0 0 0] 0; nuMax nuMax [0 2 -1 0 0 0 0] 100; } ************************************ I figured k is the constant of power law equation. (viscosity) = k * (velocity) ^ (n-1) What are nuMax and nuMin? I attached a figure of a flow curve. Are nuMax and nuMin defind like this figure? And, what is nu, then? I would be very apprecitated, if somebody could help me. |
