Journal of Physical Chemistry B, 2022 The second to eighth virial coefficients of methane were determined for temperatures up to 1200 K using an existing ab initio-based and empirically fine-tuned two-body potential combined with a new empirical nonadditive three-body potential.

Virial equation of state for a granular system
The European Physical Journal EThe equation of state for an ideal gas is simple, which is $P=nk_{\rm B}T$. In the case of imperfect gases where mutual interactions among the constituents are important, pressure $P$ can be expressed as the series expansion of density $n$ with appropriate coefficients, known as virial coefficients $B_m$.

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.

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

Short distance modification of the quantum virial theorem
Physics Letters B, 2017 In this letter, we will analyse the deformation of a semi-classical gravitational system from minimal measurable length scale. In the semi-classical approximation, the gravitational field will be analysed as a classical field, and the matter fields will ...

Thermodynamic pressures for hard spheres and closed-virial equation-of-state.
Journal of Chemical Physics, 2010 Hard-sphere molecular dynamics (MD) simulation results, with six-figure accuracy in the thermodynamic equilibrium pressure, are reported and used to test a closed-virial equation-of-state.

Eighth-order virial equation of state and speed-of-sound measurements for krypton.
Journal of Chemical Physics, 2019 An eighth-order virial equation of state (VEOS) for krypton, valid for temperatures up to 5000 K, was developed using the accurate potential functions proposed by Jäger et al. [J. Chem. Phys.
