In 1893 William Sutherland, an Australian physicist, published a relationship between the dynamic viscosity, , and the absolute temperature, , of an ideal gas. This formula, often called Sutherland's law, is based on kinetic theory of ideal gases and an idealized intermolecular-force potential.
Sutherland’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 )
The molecular viscosity is given by the Sutherland law; the eddy viscosity being derived from the considered turbulence model.
May 7, 2021 · For air, D. M. Sutherland provides an equation for the dependence on temperature T: mu = mu0 * ((T / T0)^1.5) * ((T0 + 198.72) / (T + 198.72)) where mu0 and T0 are reference values given at sea level stanfard conditions. The temperature is specified in degrees Rankine: mu0 = 3.62 x 10^-7 lb-sec/ft^2 T0 = 518.7 R
Learn how to use Sutherland's law to define the viscosity as a function of temperature in ANSYS FLUENT 12.0, a computational fluid dynamics software. Sutherland's law has two or three coefficients that depend on the mass fraction, molecular weight, and temperature of the gas.
