• Bow Shock Clustering in Particle-laden Wetted Cylinder Flow 

      Shi, Zhaoyu; Jiang, Fengjian; Strandenes, Håkon; Zhao, Lihao; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2020-09)
      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 ...
    • Clusters and coherent voids in particle-laden wake flow 

      Shi, Zhaoyu; Jiang, Fengjian; Zhao, Lihao; Andersson, Helge Ingolf (Peer reviewed; Journal article, 2021)
      Inertial point particles suspended in a two-dimensional unsteady circular cylinder flow at Re = 100 are studied by one-way coupled three-dimensional numerical simulations. The striking clustering pattern in the near-wake ...
    • Different topologies of natural vortex dislocations in Mode A wake 

      Tian, Cai; Shi, Zhaoyu; Jiang, Fengjian; Andersson, Helge Ingolf (Peer reviewed; Journal article, 2022)
      The mode A wake behind a circular cylinder at Reynolds number 200 was simulated by directly solving the three-dimensional Navier–Stokes equations. A more detailed investigation of different topologies of natural vortex ...
    • Inertial torque on a small spheroid in a stationary uniform flow 

      Jiang, Fengjian; Lihao, Zhao; Andersson, Helge Ingolf; Gustavsson, Kristian; Pumir, Alain; Mehlig, Bernhard (Peer reviewed; Journal article, 2021)
      How anisotropic particles rotate and orient in a flow depends on the hydrodynamic torque they experience. Here we compute the torque acting on a small spheroid in a uniform flow by numerically solving the Navier-Stokes ...
    • Scale-dependent particle clustering in transitional wake flow 

      Shi, Zhaoyu; Jiang, Fengjian; Zhao, Lihao; Andersson, Helge Ingolf (Peer reviewed; Journal article, 2022)
      Dispersion and mixing of inertial point particles in the unsteady and three-dimensional wake of a circular cylinder at Re=200 are investigated via one-way coupled simulations. The presence of streamwise-oriented vortical ...
    • State-of-the-Art Review of Vortex-Induced Motions of Floating Offshore Wind Turbine Structures 

      Yin, Decao; Passano, Elisabeth; Jiang, Fengjian; Lie, Halvor; Wu, Jie; Ye, Naiquan; Sævik, Svein; Leira, Bernt Johan (Peer reviewed; Journal article, 2022)
      The motivation for this study is the fast development of floating offshore wind energy and the immature methodology and engineering practice related to predictions of vortex-induced motions (VIM). Benefiting from the oil ...
    • Three-dimensional wake transition behind an elliptic cylinder near a moving wall 

      Zhu, Jianxun; Jiang, Fengjian; Holmedal, Lars Erik (Peer reviewed; Journal article, 2021)
      Three-dimensional flow past an elliptic cylinder with an aspect ratio of 0.5 near a moving bottom wall is investigated numerically for gap ratios of 𝐺/𝐷=0.1,0.2,0.3, and 0.4 (where G denotes the gap between the cylinder ...
