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 ... -
Nonlinear vacuum gas flow through a short tube due to pressure and temperature gradients
(2013)The flow of a rarefied gas through a tube due to both pressure and temperature gradients has been studied numerically. The main objective is to investigate the performance of a mechanical vacuum pump operating at low ... -
Pressure- and Temperature-Driven Flow Through Triangular and Trapezoidal Microchannels
(2011)A detailed study of pressure- and temperature-driven flows through long channels of triangular and trapezoidal cross sections is carried out. Due to the imposed pressure and temperature gradients there is a combined gas ... -
Rarefied gas flow in concentric annular tube: Estimation of the Poiseuille number and the exact hydraulic diameter
(2008)The fully developed flow of rarefied gases through circular ducts of concentric annular cross sections is solved via kinetic theory. The flow is due to an externally imposed pressure gradient in the longitudinal direction ... -
Rarefied gas flow through short tubes into vacuum
(2008)A rarefied gas flow into vacuum through a tube of finite length is investigated over the whole range of gas rarefaction by the direct simulation Monte Carlo method. The nonequilibrium effects at the inlet and outlet of the ...
