摘要

本文提出了耗散相对论流体动力学作为二阶拟线性对称双曲系统的因果五场公式。该系统由场的四个耗散系数η、ζ、κ、μ\eta、\zeta、\kappa、\mu确定，它们量化了剪切粘度、体积粘度、热导率和扩散。

A causal formulation of dissipative relativistic fluid dynamics with or without diffusion

The article proposes a causal five-field formulation of dissipative relativistic fluid dynamics as a quasilinear symmetric hyperbolic system of second order. The system is determined by four dissipation coefficients η , ζ , κ , μ \eta ,\zeta ,\kappa ,\mu , free functions of the fields, which quantify shear viscosity, bulk viscosity, heat conductivity, and diffusion.
