Plane Couette Flow of Rarefied Gases
The Physics of Fluids, 1967The thirteen-moment approximation to the molecular velocity distribution function has been used to develop a system of moment equations and boundary conditions for plane Couette flow. Following linearization, an iteration scheme is proposed for study of nonlinear aspects of the problem.

DRAG OF SPHERES IN RAREFIED HYPERVELOCITY FLOW
AIAA Journal, 1963Drag of spheres has been measured under hypersonic, cold-wall, support-free conditions in a nonreacting flow in which molecular vibration was frozen. Data were obtained for a nominal freestream Mach number of 11 and for Reynolds numbers from 1 to 10 based on conditions immediately downstream of the normal shock and sphere diameter.

COMPUTATIONAL HYPERSONIC RAREFIED FLOWS
Annual Review of Fluid Mechanics, 1998▪ Abstract Recent considerable progress in the field of rarefied hypersonic computational fluid dynamics (CFD) gives reason to address its evolution to an independent CFD branch that covers many fundamental and closely related applied problems of high-altitude aerothermodynamics of space vehicles.

Nonlinear oscillatory fully-developed rarefied gas flow in plane geometry
The Physics of Fluids, 2019The nonlinear oscillatory fully developed rarefied gas flow between parallel plates due to an external harmonic force is investigated by the Direct Simulation Monte Carlo (DSMC) method in terms of the parameters characterizing the flow, namely, the gas ...

Numerical approach and computer code are developed to study 2D rarefied gas flow in a microchannel having an elastic obstacle. A Couette rarefied gas flow passing an elastic beam clamped to the fixed bottom wall is considered as a test case. The gas flow
