Geometry-Controlled Motility of Microswimmers in elementary microfluidic confinements
Marvin Brun-Cosme-Bruny, Philippe Peyla, Salima Rafai
The motility of microswimmers in confined environments is a fundamental problem in active matter physics, with direct implications for microfluidic applications and the understandi…
Deflection of phototactic microswimmers through obstacle arrays
Marvin Brun-Cosme-Bruny, Andre Förtsch, Walter Zimmermann +3
We study the effect of inhomogeneous environments on the swimming direction of the microalgae \textit{Chlamydomonas Reinhardtii} (CR) in the presence of a light stimulus. Positive…
Extreme congestion of microswimmers at a bottleneck constriction
Marvin Brun-Cosme-Bruny, Vincent Borne, Sylvain Faure +3
When attracted by a stimulus (e. g. light), microswimmers can build up very densely at a constriction and thus cause clogging. The micro-alga \textit{Chlamydomonas Reinhardtii} is…
Effective diffusivity of microswimmers in a crowded environment
Marvin Brun-Cosme-Bruny, Eric Bertin, Benoît Coasne +2
The microalga Chlamydomonas Reinhardtii (CR) is used here as a model system to study the effect of complex environments on the swimming of micro-organisms. Its motion can be modell…
Photofocusing: Light and flow of phototactic microswimmer suspension
Matthieu Martin, Alexandre Barzyk, Eric Bertin +2
We explore in this paper the phenomenon of photofocusing: a coupling between flow vorticity and biased swimming of microalgae toward a light source that produces a focusing of the…
Effective viscosity of a suspension of flagellar beating microswimmers: Three-dimensional modeling
Levan Jibuti, Walter Zimmermann, Salima Rafaï +1
Micro-organisms usually can swim in their liquid environment by flagellar or ciliary beating. In this numerical work, we analyze the influence of flagellar beating on the orbits of…
