• 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 ...
    • Forces and torques on a prolate spheroid: low-Reynoldsnumber and attack angle effects 

      Andersson, Helge Ingolf; Jiang, Fengjian (Journal article; Peer reviewed, 2018)
      The three-dimensional flow field around a prolate spheroid has been obtained by integration of the full Navier–Stokes equations at Reynolds numbers 0.1, 1.0, and 10. The 6:1 spheroid was embedded in a Cartesian mesh by ...
    • Influences of upstream extensions on flow around a curved cylinder 

      Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2018)
      In simulations of flow around a concave curved cylinder, i.e. free-stream aligned with the plane of curvature and directed towards the inner face of the curvature, one cannot avoid interactions between the cylinder 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 ...
    • Numerisk simulering av en viskøs strømning rundt en krum sylinder i tverrstrøm 

      Mortensen, Olav Egaas (Master thesis, 2019)
      Denne masteravhandlingen presenterer numeriske undersøkelser av den tredimensjonale viskøse strømningen rundt en rett sirkulær sylinder og en krum sirkulær sylinder i tverrstrøm. Simuleringer har blitt utarbeidet i ...
    • Numerisk Simulering av strømning rundt en kurvet sylinder med varierende diameter 

      Ramsvik, Emil Severin (Master thesis, 2019)
      I denne masteroppgaven utforskes strømning rundt en konkav buet sylinder med en endring i diameter. Studien bruker direkte numerisk simulering for å løse Navier-Stokes ligningene uten bruk av turbulensmodellering. Fokuset ...
    • 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 wake behind a concave curved cylinder 

      Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2019)
      We present a detailed study of the turbulent wake behind a quarter-of-ring curved cylinder at Reynolds number Re = 3900 (based on cylinder diamter and incoming ow velocity), by means of Direct Numerical Simulation (DNS). ...
    • Wake behind a concave curved cylinder 

      Jiang, Fengjian; Pettersen, Bjørnar; Andersson, Helge Ingolf; Kim, Jongmin; Kim, Sungtae (Journal article; Peer reviewed, 2018)
      The wake behind a quarter-of-ring concave curved cylinder is investigated in this paper by means of direct numerical simulations. The plane of curvature is aligned with the uniform incoming flow. We have appended straight ...
