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…
Complex dynamics of long, flexible fibers in shear
John LaGrone, Ricardo Cortez, Wen Yan +1
The macroscopic properties of polymeric fluids are inherited from the material properties of the fibers embedded in the solvent. The behavior of such passive fibers in flow has bee…
Elastohydrodynamics of swimming helices: effects of flexibility and confinement
John LaGrone, Ricardo Cortez, Lisa Fauci
Motivated by bacterial transport through porous media, here we study the swimming of an actuated, flexible helical filament in both three-dimensional free space and within a cylind…
Regularized Stokeslet segments
Ricardo Cortez
We present a variation of the method of regularized Stokeslet (MRS) specialized for the case of forces and torques distributed over filaments in three dimensions. The new formulati…
Close evaluation of layer potentials in three dimensions
S. Khatri, A. D. Kim, Ricado Cortez +1
We present a simple and effective method for evaluating double-and single-layer potentials for Laplace's equation in three dimensions close to the boundary. The close evaluation of…
