Comparative study between computational and experimental results for binary rarefied gas flows through long microchannels
Szalmas, L.; Pitakarnnop, J.; Geoffroy, S.; Colin, S.; Valougeorgis, D. (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 ... -
DSMC simulation of binary rarefied gas flows between parallel plates and comparison to other methods
Szalmas, L. (2011)The direct simulation Monte-Carlo (DSMC) method has been developed to solve the Boltzmann equation for binary gas mixtures with hard-sphere molecules. The method is applied for pressure and concentration driven flows between ... -
DSMC simulation of pressure driven binary rarefied gas flows through short microtubes
Szalmas, L.; Valougeorgis, D.; Colin, S. (2011)Binary gas flows driven by pressure gradient through short microtubes are studied by using an upgraded version of the Direct Simulation Monte Carlo (DSMC) method. Two types of mixtures, He/Xe and Ne/Ar, are examined. Several ... -
A fast iterative model for discrete velocity calculations on triangular grids
Szalmas, L.; Valougeorgis, D. (2010)A fast synthetic type iterative model is proposed to speed up the slow convergence of discrete velocity algorithms for solving linear kinetic equations on triangular lattices. The efficiency of the scheme is verified both ... -
Flow rate measurements of binary gas mixtures through long trapezoidal microchannels
Szalmas, L.; Colin, S.; Valougeorgis, D. (2012)The flow rate of two noble gas mixtures, namely He/Ar and He/Kr, is measured through a microsystem containing 400 long trapezoidal microchannels placed in parallel configuration. Each microchannel has a trapezoidal cross ... -
Rarefied gas flow of binary mixtures through long channels with triangular and trapezoidal cross sections
Szalmas, L.; Valougeorgis, D. (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. ... -
Variance-reduced DSMC for binary gas flows as defined by the McCormack kinetic model
Szalmas, L. (2012)A variance-reduced direct simulation Monte Carlo method is presented for binary gas flows as defined by the McCormack kinetic model. Two types of flow configuration, namely pressure driven flow between two parallel plates ...
