Effects of the quiescent core in turbulent channel flow on transport and clustering of inertial particles
Yucheng Jie, Helge I. Andersson, Lihao Zhao
The existence of a quiescent core (QC) in the center of turbulent channel flows was demonstrated in recent experimental and numerical studies. The QC-region, which is characterized…
Inertial torque on a small spheroid in a stationary uniform flow
F. Jiang, L. Zhao, H. I. Andersson +3
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…
A slender body model for thin rigid fibers: validation and comparisons
Laurel Ohm, Benjamin K. Tapley, Helge I. Andersson +2
In this paper we consider a computational model for the motion of thin, rigid fibers in viscous flows based on slender body theory. Slender body theory approximates the fluid veloc…
High-order overset grid method for detecting particle impaction on a cylinder in a cross flow
J. R. Aarnes, N. E. L. Haugen, H. I. Andersson
An overset grid method was used to investigate the interaction between a particle-laden flow and a circular cylinder. The overset grid method was implemented in the Pencil Code , a…
Instabilities in the wake of an inclined prolate spheroid
Helge I. Andersson, Fengjian Jiang, Valery L. Okulov
We investigate the instabilities, bifurcations and transition in the wake behind a 45-degree inclined 6:1 prolate spheroid, through a series of direct numerical simulations (DNS) o…
