Hi. I want to solve the momentum and energy equation in non dimensional form to simulate the laminar flow and heat transfer in channel of forced convection. Please can you explain how can I define the values of properties of the fluid (mu,rho,Cp,K) in the Materials. for Re=100, Pr=0.7. Please help me, it's very important!! Thanks in advance!

You can work with any fluid (air for exemple) and then you adimensionalise your result with reference's values.

Ck3, thanks. But I want to solve the momentum and energy equation in non dimensional form to simulate the laminar flow and heat transfer in channel of forced convection , for example

Re = 200, I change the Matrial ( propriety of the fluid) : rho = 1 kg/m3, mu = 0.005 kg/(ms), u = 1 m/s . Please can you explain how can I define the values of fluid properties: Cp, K in the Materials for Re=200, Pr=0.7 and boundary condition.
