Hydrodynamic Instabilities of Active Jets
Marco Vona, Isabelle Eisenmann, Nicolas Desprat +3
Using a combination of theory, experiments, and numerical simulations, we investigate the stability of coherent structures in a suspension of strongly aligned active swimmers. We s…
Pure hydrodynamic instabilities in active jets of "puller" microalgae
Isabelle Eisenmann, Marco Vona, Nicolas Desprat +3
Active fluids can develop spontaneous flow instabilities and complex patterns. However, spatio-temporal control of active particles has remained challenging, despite its relevance…
Rotational mobility in spherical membranes: The interplay between Saffman-Delbrück length and inclusion size
Marco Vona, Eric Lauga
The mobility of particles in fluid membranes is a fundamental aspect of many biological processes. In a 1975 paper [1], Saffman and Delbrück demonstrated how the presence of exter…
Feeders and Expellers, Two Types of Animalcules With Outboard Cilia, Have Distinct Surface Interactions
Praneet Prakash, Marco Vona, Raymond E. Goldstein
Within biological fluid dynamics, it is conventional to distinguish between "puller" and "pusher" microswimmers on the basis of the forward or aft location of the flagella relative…
