Experimental study of the heat transfer problem in expansion devices in CO2 refrigeration systems
Mastrowski, Mikolaj; Smolka, Jacek; Hafner, Armin; Haida, Michal; Palacz, Michal; Banasiak, Krzysztof (Journal article; Peer reviewed, 2019)Two expansion devices designed for CO2 refrigeration systems namely, capillary tube and fixed-geometry ejector were experimentally tested in the SINTEF/NTNU laboratory in Trondheim, Norway to determine the influence of ... -
Numerical investigation of heat transfer in a CO2 two-phase ejector
Haida, Michal; Smolka, Jacek; Hafner, Armin; Mastrowski, Mikolaj; Palacz, Michal; Madsen, Kenneth B.; Nowak, Andrzej J.; Banasiak, Krzysztof (Journal article; Peer reviewed, 2018)In this paper, the influence of heat transfer in the walls of an R744 two-phase ejector on ejector performance was investigated. A numerical investigation was performed using a computational fluid dynamic (CFD) model of ...
