Complex nonlinear dynamics of area-preserving, active vesicles
Reiner Kree, Annette Zippelius
We investigate the nonlinear shape dynamics and autonomous propulsion of actively driven quasi-spherical vesicles with locally inextensible membranes at low Reynolds number. Starti…
Amoeboid swimming of active vesicles
Reiner Kree, Annette Zippelius
We investigate the shape dynamics and migration of weakly deflated active vesicles driven by processes acting either directly in the membrane or transmitted by the cytoskeleton. Fo…
Amoeboid propulsion of active solid bodies, vesicles and droplets: a comparison
Reiner Kree, Annette Zippelius
We present a unified discussion of three types of near-spherical amoeboid microswimmers, driven by periodic, axially symmetric, achiral deformations (swim strokes): a solid deforma…
Mobilities of a drop and an encapsulated squirmer
Reiner Kree, Annette Zippelius
We have analyzed the dynamics of a spherical, uni-axial squirmer which is located inside a spherical liquid drop at general position . The squirmer is subject to an exter…
Self propulsion of droplets driven by an active permeating gel
Reiner Kree, Annette Zippelius
We discuss the flow field and propulsion velocity of active droplets, which are driven by body forces residing on a rigid gel. The latter is modelled as a porous medium which gives…
From active stresses and forces to self propulsion of droplets
R. Kree, P. S. Burada, A. Zippelius
We study the self-propulsion of spherical droplets as simplified hydrodynamic models of swimming microorganisms or artificial microswimmers. In contrast to approaches, which start…
