Relativistic viscous fluid dynamics and non-equilibrium entropy

Relativistic Viscous Fluid Dynamics and Non-Equilibrium Entropy

Fluid dynamics corresponds to the dynamics of a substance in the long wavelength limit. Writing down all terms in a gradient (long wavelength) expansion up to second order for a relativistic system at vanishing charge density, one obtains the most general (causal) equations of motion for a fluid in the presence of shear and bulk viscosity, as well as the structure of the non-equilibrium entropy...

Relativistic Equilibrium Distribution by Relative Entropy Maximization

The equilibrium state of a relativistic gas has been calculated based on the maximum entropy principle. Though the relativistic equilibrium state was long believed to be the Jüttner distribution, a number of papers have been published in recent years proposing alternative equilibrium states. However, some of these papers do not pay enough attention to the covariance of distribution functions, r...

Thermostatistics of a Relativistic Gas: Equilibrium and Non-equilibrium Properties

The introduction of models to simulate dynamics of relativistic gaseous systems is among the latest efforts made in the recent decades to investigate the relativistic generalizations of statistical thermodynamics. Relativistic thermodynamics was born in the early 20th century to investigate the consequences of Einstien’s special relativity on thermodynamic systems. A simple and important questi...
