Cytoplasmic stirring by active carpets
Brato Chakrabarti, Stanislav Y. Shvartsman, Michael J. Shelley
Large cells often rely on cytoplasmic flows for intracellular transport, maintaining homeostasis, and positioning cellular components. Understanding the mechanisms of these flows i…
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-…
Fluid circulation driven by collectively organized metachronal waves in swimming T. aceiti nematodes
A. C. Quillen, A. Peshkov, Brato Chakrabarti +3
Recent experiments have shown that the nematode {\it T. aceti} can assemble into collectively undulating groups at the edge of fluid drops. This coordinated state consists of metac…
Dynamics of flexible filaments in oscillatory shear flows
Francesco Bonacci, Brato Chakrabarti, David Saintillan +2
The fluid-structure interactions between flexible fibers and viscous flows play an essential role in various biological phenomena, medical problems, and industrial processes. Of pa…
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…
Morphological transitions of elastic filaments in shear flow
Yanan Liu, Brato Chakrabarti, David Saintillan +2
The morphological dynamics, instabilities and transitions of elastic filaments in viscous flows underlie a wealth of biophysical processes from flagellar propulsion to intracellula…
Catenaries in viscous fluid
Brato Chakrabarti, J. A. Hanna
This work explores a simple model of a slender, flexible structure in a uniform flow, providing analytical solutions for the translating, axially flowing equilibria of strings subj…
