    • Flow Around Curved Tandem Cylinders 

      Aasland, Tale Egeberg; Pettersen, Bjørnar; Andersson, Helge Ingolf; Jiang, Fengjian (Peer reviewed; Journal article, 2022)
      The flow around curved tandem cylinders of equal diameter has been investigated for the first time, by means of direct numerical simulations. A convex configuration was used. The nominal gap ratio was L/D = 3.0 and a ...

    • Large Eddy Simulations of Flow around a Circular Cylinder in the Vicinity of a Wall at Reynold Number of 13100 

      Abrahamsen-Prsic, Mia; Ong, Muk Chen; Pettersen, Bjørnar; Myrhaug, Dag (Chapter, 2013)
      The flow around a circular cylinder in the vicinity of a rigid wall at Reynolds number 13100 is simulated using Large Eddy Simulations (LES) with Smagorinsky subgrid scale model. The main purpose of the present work is to ...

    • Revisiting the reattachment regime: a closer look at tandem cylinder flow at Re=10000 

      Aasland, Tale Egeberg; Pettersen, Bjørnar; Andersson, Helge Ingolf; Jiang, Fengjian (Peer reviewed; Journal article, 2022)
      Tandem cylinder flow comprises several different flow regimes. Within the reattachment regime, the development of the gap shear layers is of utmost importance to the flow, but has received little attention so far. Through ...
