Inertial clustering and emergent phase separation of spherical spinners
Zaiyi Shen, Juho S. Lintuvuori
We study the hydrodynamics of spherical spinners suspended in a Newtonian fluid at inertial regime. We observe a spontaneous condensation of the spinners into particle rich regions…
Gravity induced formation of spinners and polar order of spherical microswimmers on a surface
Zaiyi Shen, Juho S. Lintuvuori
We study numerically the hydrodynamics of a self-propelled particle system, consisting of spherical squirmers sedimented on a flat surface. We observe the emergence of dynamic stru…
Optimal cell transport in straight channels and networks
Alexander Farutin, Zaiyi Shen, Gael Prado +9
Flux of rigid or soft particles (such as drops, vesicles, red blood cells, etc.) in a channel is a complex function of particle concentration, which depends on the details of induc…
Predicting optimal hematocrit in silico
Alexander Farutin, Zaiyi Shen, Gael Prado +9
Optimal hematocrit maximizes oxygen transport. In healthy humans, the average hematocrit is in the range of 40-45, but it can significantly change in blood pathologie…
Hydrodynamic assembly of active colloids: chiral spinners and dynamic crystals
Zaiyi Shen, Alois Würger, Juho S. Lintuvuori
Active colloids self-organise to a variety of collective states, ranging from highly motile 'molecules' to complex 3D structures. Using large-scale simulations, we show that hydrod…
