dc.description.abstract | Binary gas flows driven by pressure gradient through short microtubes are studied by using an upgraded version of the Direct Simulation Monte Carlo (DSMC) method. Two types of mixtures, He/Xe and Ne/Ar, are examined. Several values of the channel length to radius ratio, the downstream to upstream pressure ratio and a wide range of the gas rarefaction are considered. Results are presented for the species and total flow rates and for the axial distributions of the macroscopic quantities. There is a pronounced difference of the flow behavior of the two mixtures due to the different molecular mass ratios. The flow rate of the He/Xe mixture for very short channels and large pressure drops is increased with increasing gas rarefaction, while the flow rate of the Ne/Ar mixture shows a different rarefaction dependence. The obtained results can be useful in optimal design of microflu-idic or vacuum devices. Copyright © 2011 by ASME. | en |
