Frontiers of Mechanical Engineering 2009, Volume 4, Issue 3,   Pages 252-263 doi: 10.1007/s11465-009-0037-6

Abstract: In micro- and nanoscale gas flows, the flow falls into the transition flow regime.The Navier-Stokes equations fail to describe the gas flow in this regime.As a result, the high-order Burnett equations are used to study the gas flow and heat transfer characteristicsin micro- and nanoscale gas flows in this paper.augmented Burnett equations with high-order slip boundary conditions are then used to model the gas flow
