在这项工作中，我们提出了一个唯象模型，以寻求更好地了解在稀单原子气体的冲击波结构。该模型是基于线性不可逆热力学的原则，我们已经意识到由冲击波传播引起的流动各向异性。在应力张量和热流之间出现了新的耦合。与氩气的实验数据以及直接模拟蒙特卡罗方法计算的比较，并支持我们的建议。
In this work we present a phenomenological model to look for a better understanding of the shock-wave structure in dilute monatomic gases. The model is based on the principles of linear irreversible thermodynamics, where we have been aware of the flow anisotropy caused by the shock-wave propagation. Then a new coupling appears between the stress tensor and the heat flux. The comparisons with the experimental data available for argon as well as the direct simulation Monte Carlo method calculations are done and shown to support our proposal.
