Abstract

The Landau–Lifshitz frame has been widely used to represent the macroscopic quantities of relativistic hydrodynamics in the presence of the dissipative process. In this paper, we derive the Landau–Lifshitz frame in the near-equilibrium regime under self-contained assumptions that do not require comparison with the Eckart frame. And then we revisit the relativistic BGK model proposed by Anderson and Witting to provide an application example of the Landau–Lifshitz frame.

相对论动力学理论中Landau–Lifshitz框架的推导

Landau–Lifshitz框架已被广泛用于表示耗散过程中相对论流体力学的宏观量。在本文中，我们在不需要与Eckart框架进行比较的独立假设下，导出了近平衡状态下的Landau–Lifshitz框架。然后，我们重新审视Anderson和Witting提出的相对论BGK模型，以提供Landau–Lifshitz框架的应用实例。
