• A CFD analysis for the performance assessment of a novel design of plates-in-tank latent storage unit for freezing applications 

      Selvnes, Håkon; Allouche, Yosr; Sevault, Alexis; Hafner, Armin (Chapter, 2019)
      In this paper, the charging and discharging processes of a recently developed cold thermal energy storage (CTES) unit integrated into a poultry processing plant is investigated. A mathematical model of the CTES was created ...
    • CFD modeling of ice formation and melting in horizontally cooled and heated plates 

      Selvnes, Håkon; Allouche, Yosr; Sevault, Alexis; Hafner, Armin (Chapter, 2019)
      This paper investigates the ice formation and melting processes in a novel CTES unit using the commercial CFD software ANSYS Fluent 19. The storage unit is designed to operate as a peak shaving device integrated into the ...
    • A detailed review on CO2 two-phase ejector flow modeling 

      Ringstad, Knut Emil; Allouche, Yosr; Gullo, Paride; Ervik, Åsmund; Banasiak, Krzysztof; Hafner, Armin (Peer reviewed; Journal article, 2020)
      Ejector-equipped vapor-compression systems for refrigeration and cooling, relying solely on (R744) as a natural working fluid, are perceived to be an eco-friendly and highly efficient solution for many applications. However, ...
