Measurement of Continuum Breakdown Using a Disc Spin-Down Experiment in Low Pressure Air
As flow becomes rarefied, a quantity called as the tangential momentum accommodation coefficient (TMAC) becomes important because it is a measure of the momentum transport from a gas molecule to a surface. Very few experimental measurements of continuum breakdown in boundary layer flows exist. All …

Isothermal helium flow measurements twrough a rectangular channel for a Wide Knudsen range
… is to measure the isothermal steady flow of Helium through a rectangular microchannel from the continuum to the free-molecular regime. The intention is to expand the measured Knudsen number range for rectangular cross section microchannels as compared with that presently found in in …

Simulation of rocket plume impingement and dust dispersal on the lunar surface
… plume impingement, transition from continuum to free molecular flow, erosion, coupled gas-dust motions, and granular collisions for a polydisperse distribution of aerosolized particles. The focus of this work is to identify and model the important physical phenomena and to characterize the dust …
