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) where Sμ is an effective temperature called the Sutherland constant. Each gas has its own Sutherland constant.
Learn about Sutherland's law, a formula for the viscosity of ideal gases based on kinetic theory and intermolecular force. Find the coefficients for different gases and the Sutherland temperature.
La ley de Sutherland describe la dependencia de la viscosidad de los gases con la temperatura. Fue propuesta en 1893 por el físico australiano William Sutherland. 1 El modelo se basa en la teoría cinética de gases, donde el efecto de la interacción intermolecular se representa por medio de un potencial. A pesar de utilizar aproximaciones ...
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.
Sutherland law is a formula for the molecular viscosity of a gas as a function of temperature. It is used in various engineering applications, such as turbulence modelling, flow separation, and aerodynamic heating.
