Thermodynamics of Polydisperse Systems

Thermodynamics of Polydisperse Systems.— The simplest polydisperse system is perhaps that composed of hard spheres (or discs) with a continuous distribution f(a-) of particle diameter cr. For a multicomponent mixture of hard spheres in the Percus-Yevick approximation, the compressibility equation of state is  [Pg.170]

In equation (61), ct is the most probable diameter, and A measures the degree of polydispersity. The difference in pIpkT between a polydisperse system having zl = 0.28 and its equivalent monodisperse system is obtained from a generalization of the Percus-Yevick mixture result of Lebowitz and Rowlin-son. At low densities A(p/pkT) is negligible but in a concentrated dispersion it could amount to several per cent. [Pg.171]

The van der Waals one-fluid approximation agrees with the Percus-Yevick result, except at very high-volume fractions. [Pg.171]

The one-fluid theory is extended to non-additive particles by defining [Pg.172]
