Semiclassical approach to model quantum fluids using the statistical associating fluid theory for systems with potentials of variable range

VM Trejos, A Gil-Villegas - The Journal of Chemical Physics, 2012 - pubs.aip.org
Thermodynamic properties of quantum fluids are described using an extended version of the
statistical associating fluid theory for potentials of variable range (SAFT-VR) that takes into
account quantum corrections to the Helmholtz free energy A, based on the Wentzel-Kramers-
Brillouin approximation. We present the theoretical background of this approach (SAFT-
VRQ), considering two different cases depending on the continuous or discontinuous nature
of the particles pair interaction. For the case of continuous potentials, we demonstrate that …
