    • Diameter ratio effects in the wake flow of single step cylinders 

      Tian, Cai; Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Peer reviewed; Journal article, 2020)
      Vortex interactions behind step cylinders with diameter ratio 2 ≤ D/d ≤ 3 at Reynolds number (ReD) 150 were investigated by directly solving the three-dimensional Navier–Stokes equations. In accordance with the previous ...

    • Different topologies of natural vortex dislocations in Mode A wake 

      Tian, Cai; Shi, Zhaoyu; Jiang, Fengjian; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2022)

    • Vortex dislocation mechanisms in the near wake of a step cylinder 

      Tian, Cai; Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Peer reviewed; Journal article, 2020)
      Vortex interactions behind step cylinders with diameter ratio D/d = 2 and 2.4 at Reynolds number ( ReD ) 150 were investigated by directly solving the three-dimensional Navier–Stokes equations. In accordance with previous ...

    • Vortex system around a step cylinder in a turbulent flow field 

      Tian, Cai; Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Peer reviewed; Journal article, 2021)
      The vortex system around the step surface of a step cylinder with a diameter ratio D/d=2 at Reynolds number (ReD) 3900 was investigated by directly solving the three-dimensional Navier–Stokes equations. Formation mechanisms ...
