非等熵气体动力学中的真空

The Vacuum in Nonisentropic Gas Dynamics

Geng Chen, Robin Young

摘要:

本文利用热力学所允许的最一般的一般方程,研究了单空间变量非等熵气体动力学中的真空。我们回顾物理约束的状态方程,并给出明确的和容易检查的条件下,真空发生在解决黎曼问题。然后,我们提出了一类模型的黎曼问题承认唯一的整体解决方案,没有真空。

英文摘要:

We investigate the vacuum in nonisentropic gas dynamics in one space variable, with the most general equation of states allowed by thermodynamics. We recall physical constraints on the equations of state and give explicit and easily checkable conditions under which vacuums occur in the solution of the Riemann problem. We then present a class of models for which the Riemann problem admits unique global solutions without vacuums.
