The Maximum Entropy Principle in Nonequilibrium Thermodynamics: A Brief History and the Contributions of Wolfgang Dreyer
Takashi Arima, Tommaso Ruggeri
We present a brief history of how the famous Maximum Entropy Principle was used as closure of moments of the Boltzmann equation. In particular, we want to remark on the important r…
Dispersion Relations of Longitudinal and Transverse Waves in a Rarefied Polyatomic Gas based on Rational Extended Thermodynamics
Takashi Arima, Tommaso Ruggeri, Masaru Sugiyama
We present a complete analysis of the dispersion relations for longitudinal and transverse waves in a rarefied polyatomic gas based on Rational Extended Thermodynamics (RET), which…
Effect of the dynamic pressure on the shock structure and sub-shocks formation in a mixture of polyatomic gases
Tommaso Ruggeri, Shigeru Taniguchi
We study the shock structure and the sub-shocks formation in a binary mixture of rarefied polyatomic gases, considering the dissipation only due to the dynamic pressure. We classif…
Eckart equations, Maxwellian iteration and Relativistic Causal Theories of Divergence type
Tommaso Ruggeri
We consider a general causal relativistic theory of divergence type in the framework of Rational Extended Thermodynamics (RET) for a compressible, possibly dense, gas. We require t…
A Complete Classification of Sub-Shocks in the Shock Structure of a Binary Mixture of Eulerian Gases with Different Degrees of Freedom
Tommaso Ruggeri, Shigeru Taniguchi
The shock structure in a binary mixture of polyatomic Eulerian gases with different degrees of freedom of a molecule is studied based on the multi-temperature model of rational ext…
Relativistic Kinetic Theory of Polyatomic Gases: Classical Limit of a New Hierarchy of Moments and Qualitative Analysis
Takashi Arima, Maria Cristina Carrisi, Sebastiano Pennisi +1
A relativistic version of the Kinetic Theory for polyatomic gas is considered and a new hierarchy of moments that takes into account the total energy composed by the rest energy an…
Molecular Extended Thermodynamics of Rarefied Polyatomic Gases with a new Hierarchy of Moments
Takashi Arima, Tommaso Ruggeri
Recently, Pennisi and Ruggeri [J Stat Phys 179, 231-246 (2020)] consider the classical limit of the relativistic theory of moments associated with the Boltzmann-Chernikov equation…
On the sub-shock formation in extended thermodynamics
Shigeru Taniguchi, Tommaso Ruggeri
In hyperbolic dissipative systems, the solution of the shock structure is not always continuous and a discontinuous part (sub-shock) appears when the velocity of the shock wave is…
Rational Extended Thermodynamics of a Rarefied Polyatomic Gas with Molecular Relaxation Processes
Takashi Arima, Tommaso Ruggeri, Masaru Sugiyama
We present a more refined version of rational extended thermodynamics of rarefied polyatomic gases in which molecular rotational and vibrational relaxation processes are treated in…
Non-Linear Maximum Entropy Principle for a Polyatomic Gas subject to the Dynamic Pressure
Tommaso Ruggeri
We establish Extended Thermodynamics (ET) of rarefied polyatomic gases with six independent fields, i.e., the mass density, the velocity, the temperature and the dynamic pressure,…
