一般匹配条件下的瞬态流体动力学：矩量法的初步研究
Transient fluid dynamics with general matching conditions: a first study from the method of moments
摘要：
最近的工作表明，匹配条件对相对论性流体动力学的一般一致性性质，如运动方程的因果性、稳定性和适定性，起着重要的作用。在本文中，我们推导出瞬态流体动力学的动力学理论，使用的是由以色列和斯图尔特提出的矩量法，而不施加一个特定的匹配条件。然后，我们研究如何运动方程和相应的输运系数的匹配条件的选择的影响。
英文摘要：
Recent works have revealed that matching conditions play a major role on general consistency properties of relativistic fluid dynamics such as causality, stability and wellposedness of the equations of motion. In this paper we derive transient fluid dynamics from kinetic theory, using the method of moments as proposed by Israel and Stewart, without imposing an specific matching condition. We then investigate how the equations of motion and their corresponding transport coefficients are affected by the choice of matching condition.
