Conductive heat transfer in rarefied polyatomic gases confined between parallel plates via various kinetic models and the DSMC method
(2015)The conductive heat transfer through rarefied polyatomic gases confined between parallel plates maintained at different temperatures is investigated. The approach is based on three kinetic models namely the Holway, Rykov ... -
Effect of nitrogen concentration, two-stage and prolonged cultivation on growth rate, lipid and protein content of Chlorella vulgaris
(2019)BACKGROUND: The effects of the initial nitrogen concentration, as well as of two-stage and prolonged cultivation on the growth rate, lipid and protein content of Chlorella vulgaris were examined. Additionally, a kinetic ... -
Gas flow towards an adsorbing planar wall subject to partial gas-surface thermal accommodation
(2016)The steady half-space single gas flow driven by an adsorbing planar wall is investigated based on the solution of the BGK kinetic model. The mass and heat transfer between the gas and the plate are characterized by the ... -
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 ... -
Modeling of time-dependent gas pumping networks in the whole range of the Knudsen number: Simulation of the ITER dwell phase
(2020)A hybrid time-dependent algorithm to simulate the transient response of gas distribution systems of arbitrary size and complexity, in the whole range of the Knudsen number, is proposed. The pressure evolution in the vessels ... -
Nonequilibrium Gas Flow and Heat Transfer in a Heated Square Microcavity
(2016)The flow of a rarefied gas in a square enclosure with one wall at high temperature and the other three walls at the same low temperature is investigated. The flow, characterized by the reference Knudsen number and ratio ... -
Validity range of linear kinetic modeling in rarefied pressure driven single gas flows through circular capillaries
(2017)The range of validity of various linear kinetic modeling approaches simulating rarefied pressure driven gas flow through circular tubes is computationally investigated by comparing the flowrates obtained by the linear ...
