From the vapor-liquid coexistence region to the supercritical fluid: the van der Waals fluid
Hongqin Liu
In this work the interface system of the van der Waals fluid is investigated by using the density gradient theory incorporated with the mean-field theory. Based on the mean-field d…
The mean-field dividing interface is united with the Widom line
Hongqin Liu
We define a mean-field crossover generated by the Maxwell construction as the dividing interface for the vapor-liquid interface area and a highly accurate density-profile equation…
Free Volume Power Law for Transport Properties of Hard Sphere Fluid
Hongqin Liu
This paper presents a study on the relationship between transport properties and geometric free volume for hard sphere (HS) system in dense fluid region. Firstly, a generic free vo…
Carnahan Starling type equations of state for stable hard disk and hard sphere fluids
Hongqin Liu
The well-known Carnahan-Starling (CS) equation of state (EoS) [1] for the hard sphere (HS) fluid was derived from a quadratic relation between the integer portions of the virial co…
Global equation of state and phase transitions of the hard disc systems
Hongqin Liu
The hard disc system plays a fundamental role in the study of two-dimensional matters [1-3]. High-precision compressibility data from computer simulations have been reported for al…
