Simulation-based equation of state of the hard disk fluid and prediction of higher-order virial coefficients

Molecular Physics, 2006
We present new molecular dynamics results for the pressure of the pure hard disk fluid up to the hexatic transition (about reduced density 0.9). The data combined with the known virial coefficients (up to $B_{10}$) are used to build an equation of state,

An International Laboratory Comparison Study on Approximating the Enthalpy of Adsorption via the Clausius‐Clapeyron Approach [PDF]

Chemphyschem
Adsorbate–adsorbent interaction is often quantified via the isosteric enthalpy of adsorption, ΔHst. Commonly, ΔHst is determined indirectly by applying the Clausius‐Clapeyron (CC) equation to adsorption isotherms collected at different temperatures. Methods in applying the CC equation are shown to be critical when comparing ΔHst between laboratories ...

Calculation of propellant gas pressure by simple extended corresponding state principle

Defence Technology, 2016
The virial equation can well describe gas state at high temperature and pressure, but the difficulties in virial coefficient calculation limit the use of virial equation.

On Using the BMCSL Equation of State to Renormalize the Onsager Theory Approach to Modeling Hard Prolate Spheroidal Liquid Crystal Mixtures

Entropy, 2021
Modifications to the traditional Onsager theory for modeling isotropic–nematic phase transitions in hard prolate spheroidal systems are presented. Pure component systems are used to identify the need to update the Lee–Parsons resummation term.

Equation of State of Four- and Five-Dimensional Hard-Hypersphere Mixtures

Entropy, 2020
New proposals for the equation of state of four- and five-dimensional hard-hypersphere mixtures in terms of the equation of state of the corresponding monocomponent hard-hypersphere fluid are introduced.

Infall near clusters of galaxies: comparing gas and dark matter velocity profiles [PDF]

, 2017
We consider the dynamics in and near galaxy clusters. Gas, dark matter and galaxies are presently falling into the clusters between approximately 1 and 5 virial radii.

Virial Approximation for Load and Loss in High-Speed Journal Bearings Using Pressurized Gases

Fluids, 2019
We consider steady, laminar, compressible lubrication flows in a high-speed two-dimensional journal bearing governed by the appropriate Reynolds equation. The thermodynamic states correspond to pressurized gases and are in the single-phase regime. Simple

Pneumatic Performance Study of a High Pressure Ejection Device Based on Real Specific Energy and Specific Enthalpy

Entropy, 2014
In high-pressure dynamic thermodynamic processes, the pressure is much higher than the air critical pressure, and the temperature can deviate significantly from the Boyle temperature.

Intermolecular model potentials and virial coefficients from acoustic data

Journal of Applied Sciences and Environmental Management, 2018
A simple method is presented for the determination of model two- and three-body intermolecular potentials from acoustic data. The method is applied to argon, nitrogen, methane, ethane and propane.
