Bodys, Jakub; Smolka, Jacek; Banasiak, Krzysztof; Palacz, Michal; Haida, Michal; Nowak, Andrzej J. (Science et technique du froid;2018-3, Chapter; Peer reviewed, 2018) -
Design and simulations of refrigerated sea water chillers with CO2 ejector pumps for marine applications in hot climates
Bodys, Jakub; Hafner, Armin; Banasiak, Krzysztof; Smolka, Jacek; Ladam, Yves (Journal article; Peer reviewed, 2018)Various system configurations have been developed to improve the R744 systems under hot ambient conditions. However, stationary land applications are characterised by negligible limits on space for system equipment, unlike ... -

Non-equilibrium approach for the simulation of CO2 expansion in two-phase ejector driven by subcritical motive pressure
Bodys, Jakub; Smolka, Jacek; Palacz, Michal; Haida, Michal; Banasiak, Krzysztof (Peer reviewed; Journal article, 2020)A non-equilibrium approach was proposed for highly accurate modelling of the expansion process during two-phase flow in the convergent-divergent motive nozzle of an R744 ejector. Comprehensive mapping of the coefficients ... -
Non-equilibrium approach in simulations of the R744 flow through the motive nozzle of the two-phase ejector
Bodys, Jakub; Smolka, Jacek; Palacz, Michał; Haida, Michal; Banasiak, Krzysztof (Science et technique du froid;, Chapter, 2020)The ejector technology for R744 systems was continuously improved over the last two decades in the area of control and design processes. The latter should be related with a significant interest on modelling approaches ... -
