守恒律系统的松弛近似已经被例如Bianchini(Commun Pure Appl Math,59:688-753,2006,[5])、Jin和Xin(Commun Pure Appl Math,48:235-276,1995,[17])、Liu(Arch Ration Mech Anal,80:1-18,1982,[19])、Yong(Basic aspects of bacterial relaxation systems,Birkhäuser,Boston,pp. 259-305,2001,[24])。本文研究了平衡律系统的相应松弛逼近。我们的驱动示例是由等温欧拉方程描述的管道中的气体流动。我们感兴趣的是当弛豫参数趋于零时的极限行为。我们给出了松弛收敛到原系统的状态的条件和反例的情况下,稳定状态依赖于空间变量。
The relaxation approximation for systems of conservation laws has been studied intensively for example by Bianchini (Commun Pure Appl Math, 59:688–753, 2006, [5]), Jin and Xin (Commun Pure Appl Math, 48:235–276, 1995, [17]), Liu (Arch Ration Mech Anal, 80:1–18, 1982, [19]), Yong (Basic aspects of hyperbolic relaxation systems, Birkhäuser, Boston, pp. 259–305, 2001, [24]). In this paper, the corresponding relaxation approximation forsystems of balance laws is studied. Our driving example is gas flow in pipelines described by the isothermal Euler equations. We are interested in the limiting behavior as the relaxation parameter tends to zero. We give conditions where the relaxation converges to the states of the original system and counterexamples for cases where the steady states depend on the space variable.
