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 ... -
End corrections for rarefied gas flows through capillaries of finite length
(2013)The influence of end effects on rarefied gas flows through moderately long capillaries is investigated by implementing the concept of effective capillary length, representing a sum of the real length of capillary and its ... -
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 ... -
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 ... -
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. ... -
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 of binary mixtures through long channels with triangular and trapezoidal cross sections
(2010)The flow of binary gas mixtures through long micro-channels with triangular and trapezoidal cross sections is investigated in the whole range of the Knudsen number. The flow is driven by pressure and concentration gradients. ... -
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 ... -
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 ... -
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 ...
