Resistance tensors for aggregate particles with Stokesian dynamics
J. Gissinger, G. Voth, B. Mehlig +1
The response of particles to low-Reynolds flow can be compactly predicted with resistance or mobility tensors. However, the difficulty of obtaining accurate values for the elements…
Bifurcations in Stokes Flow Sedimentation
Elias Huseby, Pierre Mathier, Meera Das +5
Particles whose shapes couple translation to rotation display a rich array of behaviors as they sediment at low Reynolds number. We introduce a unifying perspective in which the po…
Fluid-inertia torques from particle-shape symmetry
L. Sundberg, F. Candelier, N. Fintzi +4
Numerical simulation of particle motion in fluids at low particle Reynolds numbers is often based on empirical force and torque models obtained by fitting force and torque from ab-…
Helical Ribbons: Simple Chiral Sedimentation
Elias Huseby, Josephine Gissinger, Fabien Candelier +4
We investigate the sedimentation of chiral particles in viscous fluid flow. We identify helical ribbons as simple particles with strong translation-rotation coupling whose symmetry…
