Computational and experimental study of gas flows through long channels of various cross sections in the whole range of the Knudsen number
(2009)A computational and experimental study has been performed for the investigation of fully developed rarefied gas flows through channels of circular, orthogonal, triangular, and trapezoidal cross sections. The theoretical- ... -
Hybrid modeling of time-dependent rarefied gas expansion
(2014)The time evolution of the flow parameters in a system where gas is expanded from a high pressure chamber through a tube toward a low pressure chamber is investigated. During the process, the pressure in the two chambers ... -
Kinetic modeling of a tapered Holweck pump
(2014)The Holweck pump is a device widely used in many pumping systems. It can be a self-standing device or part of a multi-stage system, usually combined with a turbo-molecular pump (TMP). In the present work, an existing ... -
Predicting the Knudsen paradox in long capillaries by decomposing the flow into ballistic and collision parts
(2015)The well-known Knudsen paradox observed in pressure driven rarefied gas flows through long capillaries is quantitatively explored by decomposing the particle distribution function into its ballistic and collision parts. ...
