耗散系统稳定的一阶粒子框架相对论流体动力学

Stable First-order Particle-frame Relativistic Hydrodynamics for Dissipative Systems

Kyosuke Tsumura, Teiji Kunihiro

摘要:

首次在粒子框架(Eckart框架)中提出了一个稳定的一阶相对论耗散流体动力学方程。这个方程实际上是由作者和一位合作者从相对论性玻尔兹曼方程推导出来的。我们证明了平衡态相对于我们的流体动力学方程在粒子框架中描述的时间演化是稳定的。我们的方程可能是一个适当的起点,为建设二阶因果相对论流体力学,以取代Eckart的粒子流理论。

英文摘要:

We propose a stable first-order relativistic dissipative hydrodynamic equation in the particle frame (Eckart frame) for the first time. The equation to be proposed was in fact previously derived by the authors and a collaborator from the relativistic Boltzmann equation. We demonstrate that the equilibrium state is stable with respect to the time evolution described by our hydrodynamic equation in the particle frame. Our equation may be a proper starting point for constructing second-order causal relativistic hydrodynamics, to replace Eckart's particle-flow theory.
