Dear Foamers,
I have a question about consistency index of power law fluids (k) in power law viscosity model of openFoam. Due to definition of power law fluid, this parameter has the unit of (Pa.s^n). n is the power law index of fluid. In order to implementing this model to openFoam, the consistency index should be divided by density ( due to posts presented in forum) , but this can not explain the unit presented in openFoam for k: m^2/s which is independent of n !!!

Hi fluid-mech!!

I have the same doubt as you. Have you found an explanation for it?
