A chemomechanical model of sperm locomotion reveals two modes of swimming
Chenji Li, Brato Chakrabarti, Pedro Castilla +2
The propulsion of mammalian spermatozoa relies on the spontaneous periodic oscillation of their flagella. These oscillations are driven internally by the coordinated action of ATP-…
Electrohydrodynamic instabilities in freely suspended viscous films under normal electric fields
Mohammadhossein Firouznia, David Saintillan
Electrohydrodynamic instabilities of fluid-fluid interfaces can be exploited in various microfluidic applications in order to enhance mixing, replicate well-controlled patterns or…
Signatures of elastoviscous buckling in the dilute rheology of stiff polymers
Brato Chakrabarti, Yanan Liu, Olivia du Roure +2
As a stiff polymer tumbles in shear flow, it experiences compressive viscous forces that can cause it to buckle and undergo a sequence of morphological transitions with increasing…
Flexible filaments buckle into helicoidal shapes in strong compressional flows
Brato Chakrabarti, Yanan Liu, John LaGrone +5
The occurrence of coiled or helical morphologies is common in nature, from plant roots to DNA packaging into viral capsids, as well as in applications such as oil drilling processe…
Hydrodynamic synchronization of spontaneously beating filaments
Brato Chakrabarti, David Saintillan
Using a geometric feedback model of the flagellar axoneme accounting for dynein motor kinetics, we study elastohydrodynamic phase synchronization in a pair of spontaneously beating…
Transport and dispersion of active particles in periodic porous media
Roberto Alonso-Matilla, Brato Chakrabarti, David Saintillan
The transport of self-propelled particles such as bacteria and phoretic swimmers through crowded heterogeneous environments is relevant to many natural and engineering processes, f…
