    • Bow Shock Clustering in Particle-laden Wetted Cylinder Flow 

      Shi, Zhaoyu; Jiang, Fengjian; Strandenes, Håkon; Zhao, Lihao; Andersson, Helge Ingolf (Peer reviewed; Journal article, 2020)
      The inhomogeneous distributions of inertial particles in the unsteady flow around a wetted circular cylinder at Re=100 were investigated in one-way coupled three-dimensional numerical simulations. The Kármán vortex cells ...

    • Comparison of LES and DNS for the flow past a circular cylinder with fairings 

      Strandenes, Håkon; Canabes, José Patricio Gallardo; Pettersen, Bjørnar; Andersson, Helge Ingolf (Chapter; Peer reviewed, 2015)

    • Influence of spanwise no-slip boundary conditions on the flow around a cylinder 

      Strandenes, Håkon; Pettersen, Bjørnar; Andersson, Helge Ingolf; Manhart, Michael (Journal article; Peer reviewed, 2017)
      First we present high resolution large eddy simulations (LES) for the flow past a circular cylinder at Reynolds number 3900 to prove the quality of the simulations. A thorough grid convergence study is presented, and the ...

    • Low-frequency oscillations in flow past an inclined prolate spheroid 

      Strandenes, Håkon; Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2019)
      We analyse the forces on a 45∘ inclined 6:1 prolate spheroid at Reynolds number ReD = 8000. In contrast to flow at lower Reynolds numbers previously investigated, we now find a strong oscillatory behaviour in the global ...

    • Near-Wake of an Inclined 6:1 Spheroid at Reynolds Number 4000 

      Strandenes, Håkon; Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2019)
      The flow around a 6:1 prolate spheroid at 45 deg inclination angle and Reynolds number 4000 (based on the minor axis) is described. Despite the fact that the inflow is uniform and steady, the resulting wake is highly ...

    • On the Effect of Boundary Conditions on the Flow around a Cylinder in a Channel 

      Strandenes, Håkon; Canabes, José Patricio Gallardo; Pettersen, Bjørnar; Andersson, Helge Ingolf (Chapter, 2015)
      In this paper, the incompressible external flow around an offshore drilling riser with fairings at Reynolds number 5000 is used to study the effects of varying boundary conditions in numerical simulations. We use a direct ...

    • Recent Developments and New Results on The Flow Around an Inclined 6:1 Prolate Spheroid 

      Strandenes, Håkon; Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Chapter, 2017)
      In the light of new computational resources and improved simulation tools we present new simulations of the flow around an inclined 6:1 prolate spheroid. We present the development of the flow from the symmetric and laminar ...

    • Turbulent flow simulations at higher Reynolds numbers 

      Strandenes, Håkon (Doctoral theses at NTNU;2019:52, Doctoral thesis, 2019)
      This thesis presents recent advancements in direct numerical simulations of bluff body wake flows. The flow around a circular cylinder without and with special fairings have been studied, and the effect of boundary conditions ...
