Two-fluid model
From Wikipedia, the free encyclopedia
Two-fluid model is a traffic model to represent an urban non-freeway traffic network. Established around 1970s by Nobel prize winner scientist Ilya Prigogine and Robert Herman, two-fluid model of town traffic successfully explain quality of traffic in a town/city or metropolitan area.
There is also a two fluid model which helps explain the behavior of superfluid helium. This model states that there will be two components in liquid helium below its lambda point (the temperature where superfluid forms). These components are a normal fluid and a superfluid component. Each liquid has a different density and together their sum makes the total density, which remains constant. The ratio of superfluid density to the total density increases as the temperature approaches absolute zero.
