Hybrid modeling of time-dependent rarefied gas expansion
Vargas, M.; Naris, S.; Valougeorgis, D.; Pantazis, S.; Jousten, K. (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 ... -
On the effect of the boundary conditions and the collision model on rarefied gas flows
Vargas, M.; Stefanov, S.; Valougeorgis, D. (2011)In this work, the effect of the gas-surface interaction law and of the intermolecular collision model is examined by solving, using the DSMC method, the heat transfer problem between parallel plates and the non-isothermal ... -
Rarefied gas flow in a rectangular enclosure induced by non-isothermal walls
Vargas, M.; Tatsios, G.; Valougeorgis, D.; Stefanov, S. (2014)The flow of a rarefied gas in a rectangular enclosure due to the non-isothermal walls with no synergetic contributions from external force fields is investigated. The top and bottom walls are maintained at constant but ... -
Time-dependent rarefied gas flow of single gases and binary gas mixtures into vacuum
Vargas, M.; Naris, S.; Valougeorgis, D.; Pantazis, S.; Jousten, K. (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 ...
