Polymer mean spherical approximation for the fluid of flexible hard-sphere Yukawa star molecules
An extension of the product-reactant Ornstein-Zernike approach (PROZA) for the fluid of flexible star molecules is proposed and the corresponding version of the mean spherical approximation (MSA), the so-called polymer MSA (PMSA), is formulated. Using Baxter-Wertheim factorization technique, an...

for the fluid of flexible star molecules is proposed and the corresponding
version of the mean spherical approximation (MSA), the so-called polymer
MSA (PMSA), is formulated. Using Baxter-Wertheim factorization technique,
an analytical solution of the PMSA for the fluid of star molecules
with Yukawa hard-sphere interaction between the molecular segments is
derived and closed form analytical expressions for the Helmholtz free energy,
chemical potential and equation of state are presented. The structure
properties of several different versions of the star fluid model are studied. |
