Cross-stream migration of a vesicle in vortical flows
Gökberk Kabacaoğlu, Enkeleida Lushi
We use numerical simulations to systematically investigate the vesicle dynamics in two-dimensional (2D) Taylor-Green vortex flow in the absence of inertial forces. Vesicles are hig…
Scattering of biflagellate microswimmers from surfaces
Enkeleida Lushi, Vasily Kantsler, Raymond E. Goldstein
We use a three-bead-spring model to investigate the dynamics of bi-flagellate micro-swimmers near a surface. While the primary dynamics and scattering are governed by geometric-dep…
Directed collective motion of bacteria under channel confinement
Hugo Wioland, Enkeleida Lushi, Raymond E. Goldstein
Dense suspensions of swimming bacteria are known to exhibit collective behaviour arising from the interplay of steric and hydrodynamic interactions. Unconfined suspensions exhibit…
Stability and dynamics of anisotropically-tumbling chemotactic swimmers
Enkeleida Lushi
Micro-swimmers such as bacteria perform random walks known as run-and-tumbles to move up chemo-attractant gradients and as a result aggregate with others. It is also known that suc…
Microalgae scatter off solid surfaces by hydrodynamic and contact forces
Matteo Contino, Enkeleida Lushi, Idan Tuval +2
Interactions between microorganisms and solid boundaries play an important role in biological processes, like egg fertilisation, biofilm formation and soil colonisation, where micr…
Accumulation of motile elongated micro-organisms in turbulence
Caijuan Zhan, Gaetano Sardina, Enkeleida Lushi +1
We study the effect of turbulence on marine life by performing numerical simulations of motile microorganisms, modelled as prolate spheroids, in isotropic homogeneous turbulence. W…
Auto-chemotactic micro-swimmer suspensions: modeling, analysis and simulations
Enkeleida Lushi, Raymond E. Goldstein, Michael J. Shelley
Microorganisms can preferentially orient and move along gradients of a chemo-attractant (i.e., chemotax) while colonies of many microorganisms can collectively undergo complex dyna…
Collective Chemotactic Dynamics in the Presence of Self-Generated Fluid Flows
Enkeleida Lushi, Raymond E. Goldstein, Michael J. Shelley
In micro-swimmer suspensions locomotion necessarily generates fluid motion, and it is known that such flows can lead to collective behavior from unbiased swimming. We examine the c…
