Ultrarelativistic Gas with Zero Chemical Potential by Daniel Mata-Pacheco, Gonzalo Ares de Parga, Fernando Angulo-Brown

“…This is achieved by assigning a zero chemical potential to the ultrarelativistic ideal gas. The resulting behavior is similar to that of a Wien photon gas. …”

Gravitational Entropy and Inflation by Øystein Elgarøy, Øyvind Grøn

“…As a generalization of the present standard model of the Universe dominated by pressureless dust and a Lorentz invariant vacuum energy (LIVE), we first present a flat Friedmann universe model, where the dust is replaced with an ideal gas. It is shown that the pressure of the gas is inversely proportional to the fifth power of the scale factor and that the entropy in a comoving volume does not change during the expansion. …”

Dynamic stability of deformable elements of designs at supersonic mode of flow by Petr A Velmisov, Andrey V Ankilov

“…The stability of deformable element of a construction in the form of a plate-strip with its flowing by supersonic flow of ideal gas is investigated. Adopted in paper definitions of stability are consistent with the concept of stability of dynamical systems by Lyapunov. …”

An Excel Add-In for Refrigerants Properties and its Use for Optimising Multi-Stage Compression Refrigeration Cycles by Mohamed M. El-Awad

“…For superheated refrigerants, the add-in determines the enthalpy and entropy by adopting ideal-gas relationships in which the specific heat is also taken from ASHRAE data, but at a reduced pressure. …”

Visualizing probabilistic models in Minkowski space with intensive symmetrized Kullback-Leibler embedding by Han Kheng Teoh, Katherine N. Quinn, Jaron Kent-Dobias, Colin B. Clement, Qingyang Xu, James P. Sethna

“…We give formulas for these intensive symmetrized Kullback-Leibler (isKL) coordinate embeddings, and illustrate the resulting visualizations with the Bernoulli (coin-toss) problem, the ideal gas, n-sided die, the nonlinear least-squares fit, and the Gaussian fit. …”

Elementary cuspoid catastrophes as the models of phenomenological equations of state by Alexander V. Tatarenko

“…The same equation holds in the ideal gas area without using crossover. One more implication arising from the suggested approach is a singularity in the equations of state – endpoint of gas-liquid equilibrium at low pressures.…”

A hydrodynamical description of Bose liquid with fractional exclusion statistics by Zhaoyu Fei, Yu Chen

“…It is counter intuitive for ‘ideal’ gas to have a hydrodynamical description. We find that a hydrodynamical model of one-dimensional $|\Phi|^6$ theory shares the same ground state density profile, density-wave excitation, as well as the similar dynamical and statistical properties with the Calogero–Sutherland model in thermodynamic limit when their interaction strengths matches each other. …”

Revisiting the Clausius/Clapeyron Equation and the Cause of Linearity by Jason E. Thompson, Andrew S. Paluch

“…That is, starting with the Clapeyron equation one first assumes (1) that the change in compressibility upon vaporization is approximately 1, or equivalently that the vapor phase may be treated as an ideal gas where the molar volume of the vapor is much greater than that of the liquid, which may be assumed negligible. …”

Black hole scattering and partition functions by Y. T. Albert Law, Klaas Parmentier
