I am trying to perform a simulation on a Shear-thickening fluid. I know a shear-thickening behavior can be imparted to a fluid through the CrossPowerLaw constitutive relation. However the resulting vicosity-shear rate curve is a very gross approximation of a real dilatant fluid. This latter normally has a curve exhibiting a shear-thinning behavior for low and high shear rates, but shear thickening beaviour in a middle range. Is there a way to model this kind of fluid with openFoam instrinsic constitutive relations?

Thank you
