SpletFluid viscosity model is Sutherland’s Law. Pressure An initial pressure field may be specified. If none is provided, the fluid solver imposes a hydrostatic pressure drop across the domain if one or more pressure outflow boundary conditions is defined. Velocity The fluid phase velocity field has a default value of zero. Splet21. sep. 2024 · 2. Sutherland's Law seems to be a fairly well-accepted relationship between dynamic viscosity and temperature and was originally created to work for ideal gases, though it is often extended to be used for atmospheric air. μ = μ r e f T T r e f 3 / 2 ( T r e f + S T + S) T r e f = reference temperature. μ r e f = viscosity at T r e f.
