抄録

A binary mixture of rarefied gases between two parallel plates is considered. The Poiseuille flow, thermal transpiration (flow caused by a temperature gradient of the plates), and concentration-driven flow (flow caused by a gradient of concentration of the component gas) are analyzed on the basis of the linearized model Boltzmann equation with the diffuse reflection boundary condition. The analyses are performed for mixtures of virtual gases consisted of the hard-sphere or Maxwell molecules and for those of noble gases (He-Ne, He-Ar, and Ne-Ar). In the latter case, not only the fundamental molecular models (the hard-sphere and Maxwell models) but also more realistic ones (the inverse power-law potential and Lennard-Jones 12, 6 models) are assumed. By use of the results, the flux databases covering the entire ranges of the Knudsen number and of the concentration and a wide range of the temperature are constructed.
