An integral model based on slender body theory, with applications to curved rigid fibers
Helge I. Andersson, Elena Celledoni, Laurel Ohm +2
We propose a novel integral model describing the motion of curved slender fibers in viscous flow, and develop a numerical method for simulating dynamics of rigid fibers. The model…
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…
Computational geometric methods for preferential clustering of particle suspensions
Benjamin K. Tapley, Helge I. Andersson, Elena Celledoni +1
A geometric numerical method for simulating suspensions of spherical and non-spherical particles with Stokes drag is proposed. The method combines divergence-free matrix-valued rad…
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…
Treatment of solid objects in the Pencil Code using an immersed boundary method and overset grids
Jørgen R. Aarnes, Tai Jin, Chaoli Mao +3
Two methods for solid body representation in flow simulations available in the Pencil Code are the immersed boundary method and overset grids. These methods are quite different in…
