Low Knudsen number photophoresis

Journal of Aerosol Science, 1977
Abstract An analytical expression describing the photophoretic force on a spherical aerosol particle in the low Knudsen number regime is developed in terms of relevant dimensionless parameters. The effect of thermal creep as well as contributing low Knudsen number effects of gas slippage and temperature jump at the gas-particle interface are included

Molecular simulation of small Knudsen number flows [PDF]

open access: yesAIP Conference Proceedings, 2012
The direct simulation Monte Carlo (DSMC) method is a powerful particle-based method for modeling gas flows. It works well for relatively large Knudsen (Kn) numbers, typically larger than 0.01, but quickly becomes computationally intensive as Kn decreases due to its time step and cell size limitations.

Theoretical and numerical study of nanoporous evaporation with receded liquid surface: effect of Knudsen number

Journal of Fluid Mechanics, 2021
The liquid evaporation from nanoscale pores has attracted much attention from researchers due to its importance in water treatment and device cooling related applications. It is crucial to investigate the receded liquid case as the vapour flow resistance

DSMC investigation of rarefied gas flow over a 2D forward-facing step: Effect of Knudsen number

, 2021
A Forward-Facing Step (FFS) can be approximated as a simplified geometry for modeling the irregularities around space vehicles, the flow around which is often rarefied. These irregularities lead to flow separation, circulation, and re-attachment.

A Novel Approach To Predict Gas Flow in Entire Knudsen Number Regime through Nanochannels with Various Geometries

, 2021
Various unified gas flow (UGF) and apparent permeability models have been proposed to characterize the complex gas transport mechanisms in shale formations. However, such models are typically expressed as combinations of multiple gas flow mechanisms so

A novel solver for simulation of flows from continuum regime to rarefied regime at moderate Knudsen number

Journal of Computational Physics, 2020
A novel and simple solver for simulation of flows from continuum regime to rarefied regime at moderate Knudsen number is developed in this work. The present solver combines good features of gas kinetic flux solver (GKFS), discrete velocity method (DVM ...

The effects of Maxwellian accommodation coefficient and free-stream Knudsen number on rarefied hypersonic cavity flows

, 2020
A comprehensive numerical calculation has been conducted to investigate a rarefied hypersonic flow past a three-dimensional (3-D) cavity with a length-to-depth ratio of 4 using the direct simulation Monte Carlo (DSMC) method.
