    • Designing vortices in pipe flow with topography-driven Langmuir circulation 

      Ellingsen, Simen Andreas Ådnøy; Akselsen, Andreas Holm; Chan, Leon (Peer reviewed; Journal article, 2021)
      We present direct numerical simulation of a mechanism for creating longitudinal vortices in pipe flow, compared with a model theory. By furnishing the pipe wall with a pattern of crossing waves, secondary flow in the form ...

    • 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 ...

    • The role of Lagrangian drift in the geometry, kinematics and dynamics of surface waves 

      Pizzo, Nick; Lenain, Luc; Rømcke, Olav; Ellingsen, Simen Andreas Ådnøy; Smeltzer, Benjamin Keeler (Peer reviewed; Journal article, 2023)
      The role of the Lagrangian mean flow, or drift, in modulating the geometry, kinematics and dynamics of rotational and irrotational deep-water surface gravity waves is examined. A general theory for permanent progressive ...

    • 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 ...
