Analysis of the slip flow in the hydrodynamic entrance region of a 2D microchannel
Journal of Thermal Engineering, 2023 Two-dimensional developing flow in the entrance of a microchannel has been studied numer-ically. Due to its nature, a microchannel can be used in tight space applications and the length of channel can get very small values.

Near-wall effects in rarefied gas micro-flows : Some modern hydrodynamic approaches [PDF]
, 2007 Methods for simulating the critical near-wall region in hydrodynamic models of gas micro-flows are discussed. Two important non-equilibrium flow features - velocity slip at solid walls, and the Knudsen layer (which extends one or two molecular mean free ...

Capturing the Knudsen layer in continuum-fluid models of non-equilibrium gas flows [PDF]
, 2005 In hypersonic aerodynamics and microflow device design, the momentum and energy fluxes to solid surfaces are often of critical importance. However, these depend on the characteristics of the Knudsen layer - the region of local non-equilibrium existing up

Generalized Knudsen Number for Unsteady Fluid Flow
Physical Review Letters, 2017 We explore the scaling behavior of an unsteady flow that is generated by an oscillating body of finite size in a gas. If the gas is gradually rarefied, the Navier-Stokes equations begin to fail and a kinetic description of the flow becomes more appropriate.

Thermophoresis of Janus particles at large Knudsen numbers [PDF]
Physical Review Fluids, 2018 The force and torque on a Janus sphere moving in a rarefied gas with a thermal gradient are calculated. The regime of large Knudsen number is considered, with the momenta of impinging gas molecules either obtained from a Chapman-Enskog distribution or from a binary Maxwellian distribution between two opposing parallel plates at different temperature ...
