论文摘要
我们构建了一个三组分系统的PDES系统，该系统描述了一维喷嘴中的范德尔壁气体的动力学。描述了该系统的保护法。我们还规定了点对称性和当前小组分类的谎言代数。讨论了确切的不变解决方案。
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 ompute the Lie algebras of point symmetries and present group classification. Exact invariant solutions are discussed.
