Particle pairs and trains in inertial microfluidics
Christian Schaaf, Holger Stark
Staggered and linear multi-particle trains constitute characteristic structures in inertial microfluidics. Using lattice-Boltzmann simulations, we investigate their properties and…
Optimal control of colloidal trajectories in inertial microfluidics using the Saffman effect
Felix Rühle, Christian Schaaf, Holger Stark
In inertial microfluidics colloidal particles in a Poiseuille flow experience the Segré-Silberberg lift force, which drives them to specific positions in the channel cross section.…
Dissipative systems with nonlocal delayed feedback control
Josua Grawitter, Reinier van Buel, Christian Schaaf +1
We present a linear model, which mimics the response of a spatially extended dissipative medium to a distant perturbation, and investigate its dynamics under delayed feedback contr…
Elastic turbulence in two-dimensional Taylor-Couette flows
R. van Buel, C. Schaaf, H. Stark
We report the onset of elastic turbulence in a two-dimensional Taylor-Couette geometry using numerical solutions of the Oldroyd-B model, also performed at high Weissenberg numbers…
A flowing pair of particles in inertial microfluidics
Christian Schaaf, Felix Rühle, Holger Stark
A flowing pair of particles in inertial microfluidics gives important insights into understanding and controlling the collective dynamics of particles like cells or droplets in mic…
Inertial migration and axial control of deformable capsules
Christian Schaaf, Holger Stark
The mechanical deformability of single cells is an important indicator for various diseases such as cancer, blood diseases and inflammation. Lab-on-a-chip devices allow to separate…
