理想流体的相对论热力学

Relativistic thermodynamics of perfect fluids

Sylvain D. Brechet, Marin C. A. Girard

摘要:

基于Stückelberg提出的闵可夫斯基空间中的散度定理,导出了广义热力学量的相对论连续性方程。这种协变的方法导致相对论制定的第一和第二热力学定律。相对论性理想流体的能量密度和压力具有惯性,这导致热与功之间的相对论性耦合。导出了相对论惯性的相对论连续性方程。确定了欧拉方程和连续性方程中能量和动量的相对论修正。该相对论理论框架允许基于能量密度、熵密度、质量密度和数密度的相对论变换定律来严格推导温度、压力和化学势的相对论变换定律。

英文摘要:

The relativistic continuity equations for the extensive thermodynamic quantities are derived based on the divergence theorem in Minkowski space outlined by Stückelberg. This covariant approach leads to a relativistic formulation of the first and second laws of thermodynamics. The internal energy density and the pressure of a relativistic perfect fluid carry inertia, which leads to a relativistic coupling between heat and work. The relativistic continuity equation for the relativistic inertia is derived. The relativistic corrections in the Euler equation and in the continuity equations for the energy and momentum are identified. This relativistic theoretical framework allows a rigorous derivation of the relativistic transformation laws for the temperature, the pressure and the chemical potential based on the relativistic transformation laws for the energy density, the entropy density, the mass density and the number density.
