End corrections for rarefied gas flows through circular tubes of finite length
(2014)A method to take into account the influence of the inlet/outlet ends on rarefied gas flows through moderately long capillaries proposed previously [Vacuum 97, 26 (2013)] is applied to gas flows through circular tubes. The ... -
Experimental and numerical investigation in flow configurations related to the vacuum systems of fusion reactors
(2010)Vacuum flows in various configurations, which are related to fusion reactors are simulated using linear kinetic theory and the direct simulation Monte Carlo method (DSMC), in the whole range of the Knudsen number. In the ... -
Heat transfer through rarefied gases between coaxial cylindrical surfaces with arbitrary temperature difference
(2010)The problem of nonlinear heat transfer through a rarefied gas confined between concentric cylinders maintained at different temperatures is investigated. The formulation is based on the nonlinear Shakhov kinetic model ... -
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 gas flow through a cylindrical tube due to a small pressure difference
(2013)Flow of a rarefied gas through a cylindrical tube connecting two reservoirs maintained at a small pressure difference is considered using the axisymmetric version of the linearised BGK kinetic model equation subject to ... -
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 ...
