Orientation of Finite Reynolds Number Anisotropic Particles Settling in Turbulence
Anubhab Roy, Stefan Kramel, Udayshankar Menon +2
We present experimental and computational results for the orientation distributions of slender fibers and ramified particles settling in an isotropic turbulent flow. The rotational…
Folding dynamics and its intermittency in turbulence
Yinghe Qi, Charles Meneveau, Greg Voth +1
Fluid elements deform in turbulence by stretching and folding. In this work, by projecting the material deformation tensor onto the largest stretching direction, the dynamics of fo…
Inertial torque on a squirmer
F. Candelier, J. Qiu, L. Zhao +2
A small spheroid settling in a quiescent fluid experiences an inertial torque that aligns it so that it settles with its broad side first. Here we show that an active particle expe…
Lord Kelvin's isotropic helicoid
Darci Collins, Rami J. Hamati, Fabien Candelier +3
Nearly 150 years ago, Lord Kelvin proposed the isotropic helicoid, a particle with isotropic yet chiral interactions with a fluid, so that translation couples to rotation. An imple…
Emergent scar lines in chaotic advection of passive directors
Bardia Hejazi, Bernhard Mehlig, Greg A. Voth
We examine the spatial field of orientations of slender fibers that are advected by a two-dimensional fluid flow. The orientation field of these passive directors are important in…
Preferential rotation of chiral dipoles in isotropic turbulence
Stefan Kramel, Saskia Tympel, Federico Toschi +1
Particles in the shape of chiral dipoles show a preferential rotation in three dimensional homogeneous isotropic turbulence. A chiral dipole consists of a rod with two helices of o…
