英文摘要	A three-dimensional compressible numerical model of micro-channel is established with consideration of the effect of velocity slip near walls. Meanwhile the gas viscosity is modified based on the Knudsen number using Veijola's model. The model is proved to be credible by comparing with analytical data. A new non-dimensional parameter relative slip length Ls/Dh is found to be very useful for describing friction characteristics for compressible flow with slip in micro-scale. The correlation for fRe with this new non-dimensional parameter Ls/Dh is suggested.
