Application of the integro-moment method to steady-state two-dimensional rarefied gas flows subject to boundary induced discontinuities
(2008)The computational efficiency of the integro-moment method for solving steady-state two-dimensional rarefied gas flows is investigated. The two-dimensional boundary driven flow of a single gas in a cavity is used as a model ... -
Comparative study between computational and experimental results for binary rarefied gas flows through long microchannels
(2010)A comparative study between computational and experimental results for pressure-driven binary gas flows through long microchannels is performed. The theoretical formulation is based on the McCormack kinetic model and the ... -
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- ... -
Discrete velocity modelling of gaseous mixture flows in MEMS
(2004)The need of developing advanced micro-electro-mechanical systems (MEMS) has motivated the study of fluid-thermal flows in devices with micro-scale geometries. In many MEMS applications the Knudsen number varies in the range ... -
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 a triangular duct based on a boundary fitted lattice
(2008)The rarefied fully developed flow of a gas through a duct of a triangular cross section is solved in the whole range of the Knudsen number. The flow is modelled by the BGK kinetic equation, subject to Maxwell diffuse ... -
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 ... -
Shear driven micro-flows of gaseous mixtures
(2006)A mesoscale kinetic-type approach is proposed to solve shear driven micro flows of binary gas mixtures in MEMS. The coupled linear integro-differential equations, which formally describe the flow, are solved using the ...
