SIMULATION OF RAREFIED GAS FLOW IN MICROCHANNEL BASED ON VORTICITY-STREAM FUNCTION METHOD

摘要：

Vorticity-stream function method is successfully used to solve an incompressible gas flow in the parallel-plates micro- channel. A new formula in finite difference scheme is developed to describe the boundary vorticity based on the slip boundary theory and Taylor series expansion. Results show that the boundary vorticity are not only influenced by the Knudsen number (Kn) but also influenced by the tangential momentum accommodation coefficient (TMAC).
