Abstract
The main goal in this study is to provide deep physical descriptions on the behaviour of supersonic micro-/nano-channel flow using the direct simulation Monte Carlo method. We found some unique physical aspects of micro-/nano-flows including mixed supersonic–subsonic regimes in constant-area ducts. This mixed regime is due to the formation of entrance shocks and their reflection from the thick boundary layer developed in a rarefied medium. We studied the effects of Mach number, channel aspect ratio and flow rarefaction on the channel inflow condition. The effects of wall thermal state on flow behaviour and shock wave structures were also investigated.
