Journal ArticleDOI
Analytical solution of gaseous slip flow in long microchannels
TL;DR: In this paper, the Navier-Stokes equations for gaseous slip flow in long microchannels with a second-order accurate slip boundary condition at the walls were analyzed.
Journal ArticleDOI
Pressure-driven diffusive gas flows in micro-channels: from the Knudsen to the continuum regimes
TL;DR: In this article, the authors revisited the problem of micro-channel compressible gas flows and showed that the axial diffusion of mass engendered by the density (pressure) gradient becomes increasingly significant with increased Knudsen number compared to the pressure driven convection.
Journal ArticleDOI
Modeling of Knudsen Layer Effects in Micro/Nanoscale Gas Flows
TL;DR: In this paper, a power-law based effective mean free path (MFP) model was proposed for the transition-regime flows typical of gas micro/nanodevices.
Journal ArticleDOI
Predicting microscale gas flows and rarefaction effects through extended Navier–Stokes–Fourier equations from phoretic transport considerations
TL;DR: In this paper, an extended continuum-based approach for analyzing micro-scale gas flows over a wide range of Knudsen number and Mach number was proposed, which implicitly takes care of the complexities in the flow physics in a thermo-physically consistent sense.
Journal ArticleDOI
Molecular free path distribution in rarefied gases
TL;DR: In this article, the distribution of molecular free paths in rarefied gases using molecular dynamics simulations was investigated and it was shown that the free paths most closely follow a power-law distribution.
