摘要：
This paper reports the outcome of our recent effort in prediction of gas slip flow through microchannels. Slip Nitrogen flow through short (L/h=20) and long (L/h=2500) microchannels is analyzed and discussed using spectral element method and the generalize slip model boundary condition of Kamiadakis and Beskok [1]. The well-known curvature in pressure distribution, due to the compressible behavior of the gas flow, is observed. Comparison of numerical results (for density and pressure variation as well as the slip velocity distribution with the experimental and DSMC data as well as reported numerical results showed that the generalize slip model is able to produce reliable results for both short and long microchannels.
