Abstract

We construct a three-component system of PDEs describing dynamics of van der Walls gas in one-dimensional nozzle. The group of conservation laws for this system is described. We also compute the Lie algebras of point symmetries and present group classification. Examples of exact invariant solutions are given.

一维喷嘴中气体行为的几何研究(范德华气体的情况)

摘要

我们构建了一个三组分PDE系统,该系统描述了一维喷嘴中范德华斯气体的动力学。描述了该系统的一组守恒定律。我们还计算点对称性的李代数和当前的组分类。给出了精确不变解的例子。
