Theory
Sutherland law (gases):
$$\mu = \mu_0 \frac{T_0 + C}{T + C}\left(\frac{T}{T_0}\right)^{3/2}$$Vogel equation (liquids):
$$\ln\mu = A + \frac{B}{T + C}$$Kinematic viscosity: $\nu = \mu / \rho$ Prandtl number: $Pr = \mu c_p / \lambda$
Temperature T in Kelvin [K] for calculations; display in Celsius [°C].
CFD Usage: Use the μ(T) values to configure OpenFOAM
Sutherland / polynomial transport models or Fluent Viscosity Law inputs. Multi-fluid comparison aids working fluid selection for heat exchangers and hydraulic systems.
