• Direct numerical simulation of spray droplet evaporation in hot turbulent channel flow 

      Lupo, Giandomenico; Gruber, Andrea; Brandt, Luca; Duwig, Christophe (Peer reviewed; Journal article, 2020)
      We perform a direct numerical simulation (DNS) of 14081 “cold” spherical droplets evaporating in a “hot” fully-developed turbulent channel flow. This effort is the first extensive computation that employs four-way coupling ...
    • Heat transfer and pressure drop of supercritical CO2 in brazed plate heat exchangers of the tri-partite gas cooler 

      Zendehboudi, Alireza; Ye, Zuliang; Hafner, Armin; Andresen, Trond; Skaugen, Geir (Peer reviewed; Journal article, 2021)
      The heat transfer characteristic of supercritical CO2 is an essential research topic due to its significant influence on the performance of heat exchangers and systems. In this paper, the heat transfer and pressure drop ...
    • On heat transfer in Bödewadt flow 

      Rahman, Muhammad; Andersson, Helge Ingolf (Journal article, 2017)
      Heat transfer in revolving Bo¨dewadt flow above a planar surface has been considered. We have shown that a similarity solution of the thermal energy problem does not exist as long as the surface is impermeable. The failure ...
    • On the scaling of convective boiling heat transfer coefficient 

      Paul, Subhanker; Fernandino, Maria; Dorao, Carlos Alberto (Peer reviewed; Journal article, 2021)
      Flow boiling has been widely used during the last century, but the key mechanisms controlling the heat transfer process still remain elusive. In the particular case of convective flow boiling inside a heated pipe, most of ...
    • Simple and general correlation for heat transfer during flow condensation inside plain pipes 

      Dorao, Carlos Alberto; Fernandino, Maria (Journal article; Peer reviewed, 2018)
      This work proposes a new general and simple model to determine the local flow condensation heat transfer coefficient inside plain pipes. The model considers two regimes corresponding to high mass fluxes and/or high ...
    • Thermophoresis and its effect on particle impaction on a cylinder for low and moderate Reynolds numbers 

      Haugen, Nils Erland L; Krüger, Jonas; Aarnes, Jørgen Røysland; Karchniwy, Ewa Malgorzata; Klimanek, Adam (Peer reviewed; Journal article, 2021)
      The effect of thermophoresis on the impaction of particles on a cylinder is investigated for different particle sizes, particle conductivities, temperature gradients and for Reynolds numbers between 100 and 1600. This is ...
