Dynamical pressure for fluid mixtures with several temperatures
Published online by Cambridge University Press: 05 August 2009
Abstract
We consider binary mixtures of fluids with components having different temperatures. A new dynamical pressure term is associated with the difference of temperatures between components even if bulk viscosities are null. The non-equilibrium dynamical pressure can be measured and may be convenient in several physical situations as for example in cosmological circumstances where a dynamical pressure played a major role in the evolution of the early universe.
