On the Boltzmann Diffusion of Two Gases
We study the Boltzmann equation for a mixture of two gases in one space dimension with initial condition of one gas near vacuum and the other near a Maxwellian equilibrium state. A qualitativequantitative mathematical analysis is developed to study this mass diffusion problem based on the Green’s function of the Boltzmann equation for the single species hard sphere collision model in [13]. The ...
متن کاملDiffusion in Granular Gases of Viscoelastic Particles
Abstract. In most of the literature on granular gases it is assumed that the restitution coefficient ǫ, which quantifies the loss of kinetic energy upon a collision is independent on the impact velocity. Experiments as well as theoretical investigations show, however, that for real materials the restitution coefficient depends significantly on the impact velocity. We consider the diffusion proc...
متن کاملSupersaturation by counterperfusion and diffusion of gases.
Gaseous supersaturation can be induced under steady-state conditions when two inert gases are transmitted in opposite directions across any system comprising a diffusion barrier adjacent to a zone of limited convective capacity. This has many implications for bubble formation in vivo and can explain the occurence of symptoms of decompression sickness without decompression.
متن کاملDiffusion of Rarified Gases in Silicon Nanotubes
1. Introduction Transport of molecules in confined spaces is one of the fundamental problems still requiring theoretical description. The so far existing theories, starting with the Knudsen prediction for diffusion of non-interacting gases in long capillary tubes and subsequent classical theories do not properly capture the effects of interactions of molecules with the pore walls. Recent comput...
متن کاملAbnormal Diffusion in Wind-tree Lattice Gases
It is found numerically that a two-dimensional left-turning particle-scatterer system does not diffusefor scatterer densities slightly above one-half, or greater. For smaller densities, the diffusion coefficient is much lower than what the Boltzmann approximation predicts; this is caused by orbiting events. An isotropic-scattering model with reflective impurities also shows deviations from the ...
