    • Dynamics of disk-like particles in turbulent vertical channel flow 

      Yuan, Wenjun; Andersson, Helge Ingolf; Zhao, Lihao; Challabotla, Niranjan Reddy; Deng, Jianqiang (Journal article; Peer reviewed, 2017)
      The dynamical behavior of inertial disk-like particles in turbulent vertical channel flow is investigated by an Eulerian–Lagrangian point-particle approach. Gravity effects on distribution, translation, rotation and ...

    • Experimental study of turbulent flow with dispersed rod-like particles through optical measurements 

      Abbasi Hoseini, Afshin (Doctoral Theses at NTNU, 1503-8181; 2014:194, Doctoral thesis, 2014)
      The knowledge of the behavior of non-spherical particles suspended in turbulent flows covers a wide range of applications in engineering and science. Dispersed two-phase flows and turbulence are the most challenging subjects ...

    • Particle segregation in turbulent Couette-Poiseuille flow with vanishing wall shear 

      Yang, Kun; Zhao, Lihao; Andersson, Helge Ingolf (Journal article, 2017)
      Inertial particles dispersed in wall-bounded flows in pipes and channels are known to accumulate close to the walls. The segregation ability depends greatly on the inertia-selection effects of the near-wall quasi-coherent ...

    • Preferential orientation of tracer spheroids in turbulent channel flow 

      Jie, Yucheng; Zhao, Lihao; Xu, Chunxiao; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2019)
      Axis-symmetric spheroids, such as rod-like and disk-like particles, have been found to orient preferentially in near-wall turbulence by both experiment and numerical simulation. In current work we examined the orientation ...

    • Preferential particle concentration in wall-bounded turbulence with zero skin friction 

      Yang, Kun; Zhao, Lihao; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2017)
      Inertial particles dispersed in turbulence distribute themselves unevenly. Besides their tendency to segregate near walls, they also concentrate preferentially in wall-parallel planes. We explore the latter phenomenon in ...

    • Role of Transient Characteristics in Fish Trajectory Modeling 

      Gao, Zhu; Zuhao, Zhou; Andersson, Helge Ingolf (Journal article; Peer reviewed, 2020)
      In this experiment, we analyzed live fish (silver carp) trajectories recorded in an experimental vertical-slot fishway. Combined with a numerical simulation, we demonstrated that randomness shown in fish trajectories might ...
