Computation of the effective area and associated uncertainties of non-rotating piston gauges FPG and FRS
(2019)The effective areas of three force-balanced piston gauges (FPGs) and two Furness Rosenberg standards (FRS) in the operating pressure range of each device varying for 1 Pa-15 kPa have been accurately computed both in the ... -
Estimation of the Poiseuille number in gas flows through rectangular nano- and micro-channels in the whole range of the Knudsen number
(2009)Based on a recent work (Valougeorgis, Phys. Fluis 19(9):091701.1-091701.4, 2007), the Poiseuille number for gas flows through channels of orthogonal cross sections is estimated in the whole range of the Knudsen number from ... -
Gas-surface interaction in rarefied gas flows through long capillaries via the linearized Boltzmann equation with various boundary conditions
(2022)Reliable gas–surface interaction modeling is of major importance in consistent simulation of rarefied gas flows with applications in vacuum technology and micro-electromechanical systems. The effectiveness of the most ... -
Pulsatile pressure driven rarefied gas flow in long rectangular ducts
(2018)The pulsatile pressure driven fully developed flow of a rarefied gas through an orthogonal duct is investigated, based on the time-dependent linear Bhatnagar, Gross, and Krook equation, by decomposing the flow into its ... -
Results on the viscous slip coefficient for binary gas mixtures
(2008)The viscous slip coefficients for the binary gas mixtures of Ne-Ar, He-Ar and He-Xe are estimated by solving the McCormack kinetic model equation subject to Maxwell diffuse-specular scattering boundary conditions. The ...
