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 ... -
Computational investigation and parametrization of the pumping effect in temperature-driven flows through long tapered channels
(2017)The temperature-driven rarefied gas flow and the associated pumping effects through long channels with linearly diverging or converging cross sections are computationally investigated. The implemented kinetic modeling is ... -
Conductive heat transfer in rarefied binary gas mixtures confined between parallel plates based on kinetic modeling
(2018)The kinetic model introduced by Kosuge (2009) is implemented to solve heat transfer through rarefied binary gas mixtures confined between two parallel plates maintained at different temperatures. The results have been found ... -
Pressure and temperature driven fully-developed rarefied gas flow in a channel with uniform injection/suction through its permeable walls
(2021)The pressure and temperature driven fully-developed rarefied gas flow between two parallel permeable plates, with uniform gas injection and suction from the bottom and top plates respectively, is investigated, based on the ... -
Pressure driven rarefied gas flow through a slit and an orifice
(2012)The flow of a monatomic gas through a slit and an orifice due to an arbitrarily large pressure difference is examined on the basis of the nonlinear Bhatnagar-Gross-Krook (BGK) model equation, subject to Maxwell diffuse ... -
Rarefied isothermal gas flow in a long circular tube due to oscillating pressure gradient
(2018)The time-dependent isothermal fully developed rarefied gas flow in a circular tube driven by harmonically oscillating pressure gradient is investigated, based on the linearized unsteady BGK kinetic model equation. The flow ... -
Steady planar Couette flow of rarefied binary gaseous mixture based on kinetic modeling
(2019)The planar Couette flow of binary gaseous mixtures is studied on the basis of the kinetic model introduced by Kosuge (2009). The calculations were carried out for a wide range of the gas rarefaction, various values of the ... -
Time-dependent rarefied gas flow of single gases and binary gas mixtures into vacuum
(2014)Time-dependent flows of single gases and binary gas mixtures with various molar fractions from a chamber through a short tube into vacuum are examined by simulations and experiments. The main goal is the comparison of the ... -
Unsteady vacuum gas flow in cylindrical tubes
(2011)The starting gas flow in a cylindrical channel is investigated in the whole range of the Knudsen number by numerically solving the governing time dependent kinetic equations in a fully deterministic manner. The gas is ...
