Journal ArticleDOI
A computational model of a transcritical R744 ejector based on a homogeneous real fluid approach
TL;DR: In this paper, a mathematical model of the compressible transonic single and two-phase flow of a real fluid is discussed, in which the specific enthalpy, instead of the temperature, is an independent variable.
Journal ArticleDOI
CFD-based shape optimisation of a CO2 two-phase ejector mixing section
Michal Palacz,Jacek Smolka,Waclaw Kus,Adam Fic,Zbigniew Buliński,Andrzej J. Nowak,Krzysztof Banasiak,Armin Hafner +7 more
TL;DR: In this paper, the geometry of a CO2 ejector mixing section was optimized using genetic algorithm (GA) and an evolutionary algorithm (EA) with a validated CFD model based on the homogeneous equilibrium model (HEM).
Journal ArticleDOI
A CFD-based investigation of the energy performance of two-phase R744 ejectors to recover the expansion work in refrigeration systems: An irreversibility analysis
Krzysztof Banasiak,Michal Palacz,Armin Hafner,Zbigniew Buliński,Jacek Smolka,Andrzej J. Nowak,Adam Fic +6 more
TL;DR: In this article, a validated CFD tool was used to investigate three cases that were differentiated by the mass flow rate per unit area (mass flux) that passed through the mixer, which represented three dissimilar flow patterns.
Journal ArticleDOI
Application range of the HEM approach for CO2 expansion inside two-phase ejectors for supermarket refrigeration systems
Michal Palacz,Jacek Smolka,Adam Fic,Zbigniew Buliński,Andrzej J. Nowak,Krzysztof Banasiak,Armin Hafner +6 more
TL;DR: In this paper, the accuracy of the homogeneous equilibrium (HEM) applied to 3D CFD-based simulations of CO2 expansion inside two-phase ejectors is presented.
Journal ArticleDOI
Experimentally validated CFD analysis on sampling region determination of average indoor carbon dioxide concentration in occupied space
TL;DR: In this article, the authors tried to find representative measuring area of mean CO2 concentration in a particular room with one sleeping person using numerical modeling and found that simplified exhalation compared to a full breathing model of the person is enough precise for accurate CO2 distribution analyses.
