Increase in Axial Compressibility in a Spinning Van der Waals Gas [PDF]

Entropy, 2021
We investigated the adiabatic compression along the axial direction of a spinning Van der Waals gas by applying theoretical analysis and molecular dynamics (MD) simulations.

Rényi’s Entropy, Statistical Order and van der Waals Gas [PDF]

Entropy, 2022
The notion of statistical order derives from the disequilibrium concept introduced by López-Ruiz, Mancini, and Calbet thirty years ago. In this effort, it is shown that the disequilibrium is intimately linked to the celebrated Rényi entropy.

On the van der Waals Gas, Contact Geometry and the Toda Chain [PDF]

Entropy, 2018
A Toda–chain symmetry is shown to underlie the van der Waals gas and its close cousin, the ideal gas. Links to contact geometry are explored.

Detonation in van der Waals Gas

Fluids, 2023
Solving problems of detonation control is associated with obtaining detailed information about the gas dynamics accompanying the detonation process. This paper focuses on the dynamics of real gas flow through a plane detonation wave.

Thermodynamic extended phase space and $$P-V$$ P-V criticality of black holes at Pure Lovelock gravity

European Physical Journal C: Particles and Fields, 2020
In this work the chemistry of asymptotically AdS black hole, for the charged and uncharged solutions of Pure Lovelock gravity, is discussed. The charged case behaves as a Van der Waals fluid and whose first order phase transitions, between small stable ...

Dirac Field, van der Waals Gas, Weyssenhoff Fluid, and Newton Particle

Foundations
This article considers the Dirac field in polar formulation and shows that when torsion is taken in effective approximation the theory has the thermodynamic properties of a van der Waals gas.

An Analytical Investigation of Natural Convection of a Van Der Waals Gas over a Vertical Plate

Fluids, 2021
The study focused on a theoretical study of natural convection in a van der Waals gas near a vertical plate. A novel simplified form of the van der Waals equation derived in the study enabled analytical modeling of fluid flow and heat transfer ...

An Integral Method for Natural Convection of Van Der Waals Gases over a Vertical Plate

Energies, 2021
This paper focuses on a study of natural convection in a van der Waals gas over a vertical heated plate. In this paper, for the first time, an approximate analytical solution of the problem was obtained using an integral method for momentum and energy ...
