Flow of Gas Mixtures through Micro Channel
Details
To investigate flow of gas mixture through micro channel accurately, we have determined the accommodation coefficients of each species (argon and xenon) for gaseous mixtures by combining -MD and DSMC simulation. These obtained accommodation coefficients were applied for the flow simulation of gas mixture in micro channel, and influence of the surface with adsorbates on the flux rates was investigated. The simulation results show that velocity slip and accommodation coefficients for gas mixtures differ from that for a single gas. The differences of the molar concentration and wall characteristics lead to the variations of the flux rates in the channel.
