OpenFOAM 2.2.0: Thermophysical Modelling OpenFOAM

SpletSutherland’s law, or Sutherland’s formula, is an approximation for how the viscosity of gases depends on the temperature. This law is based on an idealized intermolecular-force potential and reads ( Ref. 5) (6-7) where Sμ is an effective temperature called the Sutherland constant. Each gas has its own Sutherland constant.
