Research Abstract |
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.
