Abstract In this paper, flow of slightly rarefied compressible nitrogen in microchannels
has been investigated numerically for low values of Reynolds and Mach numbers. The
2D governing equations were solved using Finite Element Method with first-order slip
boundary conditions (Comsol Multiphysics software). A validation was performed by
comparing with similar configuration from the literature. It was found that our model
can accurately predict the pressure driven flow in microchannels. Several interesting
findings are reported about the Relative pressure, longitudinal velocity, Mach number,
effect of gas rarefaction and flow rate. More >
