项目摘要
The present research aims at extending the conventional fluid dynamics to describe the gas behavior in the pressure range from 1 to about 1/10000 atmospheric pressure. This is an extension of the existing theory for time-independent cases to the theory for time-dependent cases. It is found that a new term should be added to the fluid-dynamic type equations due to the compressibility of the gas. A new phenomenon that is peculiar to the time-dependent systems are also found. From a technical viewpoint, the present research makes use of a new methodology that is base on a symmetric property of the Boltzmann equation, the equation which is the fundamental equation for a microscopic description of the gas. A numerical method has been newly developed in order to overcome some mathematical difficulties.
本研究旨在扩展传统的流体动力学,以描述从1到约1/10000大气压范围内的气体行为。这是现有的理论与时间无关的情况下,时间依赖的情况下的理论的扩展。结果表明,由于气体的可压缩性,流体动力学方程中应增加一项。从技术的角度来看,本研究利用了一种新的方法,该方法基于Boltzmann方程的对称性,该方程是微观描述气体的基本方程。为了克服某些数学上的困难,最近发展了一种数值方法。
