      Direct numerical simulations of Rayleigh–Bénard convection in water with non-Oberbeck–Boussinesq effects 

      Demou, Andreas D.; Grigoriadis, Dimokratis G. E. (2019)
      Rayleigh–Bénard convection in water is studied by means of direct numerical simulations, taking into account the variation of properties. The simulations considered a three-dimensional (3-D) cavity with a square cross-section ...

      Numerical study of thermally-driven flows with variable properties 

      Demou, Andreas D. (Πανεπιστήμιο Κύπρου, Πολυτεχνική Σχολή / University of Cyprus, Faculty of Engineering, 2019-07)
      Οι ροές φυσικής συναγωγής μπορούν να θεωρηθούν προσεγγιστικά ως ροές με σταθερές ιδιότητες μόνο όταν οι θερμοκρασιακές διαφορές είναι σχετικά μικρές. Σε τέτοιες περιπτώσεις, η προσέγγιση Oberbeck-Boussinesq ...

      Variable property DNS of differentially heated cavities filled with air 

      Demou, Andreas D.; Grigoriadis, Dimokratis G. E. (2020)
      Direct numerical simulations (DNS) of the thermally-driven flow of air inside differentially heated cavities (DHC) are presented. The variation of air properties is taken into account using the low-Mach approximation, to ...
