Pressure-enthalpy driven molecular dynamics for thermodynamic property calculation II: applications

摘要

The pressure-enthalpy driven molecular dynamics technique, developed in a companion paper [1], is used to compute various thermodynamic properties for the Lennard-Jones (LJ) fluid. These properties include the vapor-liquid coexistence curve, the critical point, the Joule-Thomson coefficient and inversion curve, and a complete vapor-compression refrigeration (VCR) cycle. The technique provides a simple and effective means of utilizing molecular dynamics to sample different thermodynamic state points. Results are as accurate as those obtained using Monte Carlo (MC) methods. (C) 2002 Elsevier Science B.V. All rights reserved. [References: 20]
