Hello, It is the first time that I propose a question, I hope that I would find an answer. In fact , I use CFD-ACE and I like to introduce a fluid which has a viscosity for a fluid with power law [ Shear stess = K. (shear rate)^N ]. But in CFD-ACE, I find much constant which corresponds to viscosity calculated by a law of power [ Mu0, N, D0, K, A1, A2, A3, A4, B ] I do not understand the significance of all these constants? how I write viscosity according to these constants? Thank you

check some book about nonnewton fluid such as viscous fluid flow. i am using CFDRC too. You also can check their manual or just write to them.
