Couette flow with heat transfer in the whole range of the Knudsen number
(2008)The steady-state one-dimensional flow of a gas between two parallel plates moving with relative velocity and maintained at different temperatures is examined on the basis of the non-linear Bhatnagar-Gross-Krook (BGK) model ... -
Design of micro distribution systems consisting of long channels with arbitrary cross sections
(2012)Gas flows through long micro-channels of various cross sections have been extensively investigated over the years both numerically and experimentally. In various technological applications including microfluidics, these ... -
Estimation of the Poiseuille number in gas flows through rectangular nano- and micro-channels in the whole range of the Knudsen number
(2009)Based on a recent work (Valougeorgis, Phys. Fluis 19(9):091701.1-091701.4, 2007), the Poiseuille number for gas flows through channels of orthogonal cross sections is estimated in the whole range of the Knudsen number from ... -
Modeling of complex gas distribution systems operating under any vacuum conditions: Simulations of the ITER divertor pumping system
(2016)An integrated software tool for modeling and simulation of complex gas distribution systems operating under any vacuum conditions is presented and validated. The algorithm structure includes (a) the input geometrical and ... -
Oscillatory heating in a microchannel at arbitrary oscillation frequency in the whole range of the Knudsen number
(2012)The oscillatory heating in a microchannel is investigated on the basis of linear kinetic theory. In particular, the linearized unsteady Shakhov kinetic model, subject to Maxwell boundary conditions is numerically solved ... -
Simulation of gaseous microscale transport phenomena via kinetic theory
(2010)Kinetic theory of gases, as described by the Boltzmann or model kinetic equations, provides a solid theoretical approach for solving microscale transport phenomena in gases. Due to significant advancement in computational ...
