The investigation of microswimmer dynamics provides key insights in the design of active microfluidic systems and opens doors for further studies on inertial active matter. The authors establish a theoretical foundation for the dynamics of microswimm

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. An external force applied along the microchannel induces a cross-str

We perform hydrodynamic simulations using the method of multi-particle collision dynamics and a theoretical analysis to study a single squirmer microswimmer at high Péclet number, which moves in a low Reynolds number fluid and under gravity. The rel

Squirmers that are bottom-heavy experience a torque that aligns them along the vertical so that they swim upwards. In a suspension of many squirmers, they also interact hydrodynamically via flow fields that are initiated by their swimming motion and

Abstract. We present the results of hydrodynamic simulations using the method of multi-particle collision dynamics for a system of squirmer microswimmers moving under the influence of gravity at low Reynolds numbers. In addition, the squirmers are bo

We present a hydrodynamic study of a monolayer of squirmer model microswimmers confined to a boundary by strong gravity using the simulation method of multi-particle collision dynamics. The squirmers interact with each other via their self-generated

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 microfluidic devices. They are applied in medical cell analysis and engin

Mithilfe von Computersimulationen untersucht Felix Rühle die Dynamik von Teilchenkollektiven, speziell von Paaren, unter der Voraussetzung mittlerer Reynoldszahlen, bei denen ein laminarer Fluss seine kinematische Reversibilität verliert und Trägh
Active particles, which interact hydrodynamically, display a remarkable variety of emergent collective phenomena. We use squirmers to model spherical microswimmers and explore the collective behavior of thousands of them under the influence of strong

Mithilfe der Lattice-Boltzmann-Methode konnten wir die Liftkraftprofile und Trajektorien von Teilchenpaaren in der inertialen Mikrofluidik aufnehmen. Die lateralen Fokuspositionen der Teilchenbahnen, ihre Stabilitat, sowie die Form des Kraftprofils h
