Rarefied Gas Flow Through a Slit
Physics of Fluids
The transition from near free molecule flow to slow viscous continuum flow through a slit has been studied experimentally. The measurements have been compared with the results of a theoretical analysis of the expected flow through a slit with zero length in the flow direction.
