Critical scaling and soft granular rheology of frictionless non-Brownian suspensions across jamming
Rohan Vernekar, Romain Mari, Bruno Chareyre +1
We carry out 3D computer simulations to study suspension rheology across the jamming transition for deformable non-Brownian frictionless particles. The simulations are carried out…
Energetics, shearing and pumping efficiency of propagating contractions over villi-patterned wall
Rohan Vernekar, Claude Loverdo, Stéphane Tanguy +1
Intestinal villi undergo pendular-wave motility -- an active, propagating tissue motion driven by underlying longitudinal muscles. This motility drives irreversible, counter-wave f…
Intestinal villi and crypt density robustly maximizes nutrient absorption
Martin Garic, Rohan Vernekar, Dácil I. Yánez Martín +3
The villi and crypts of the gastrointestinal tract increase the effective surface area of the intestinal mucosa, potentially enhancing nutrient absorption. It is commonly assumed t…
Hydrodynamics in a villi-patterned channel due to pendular-wave activity
Rohan Vernekar, Faisal Ahmad, Martin Garic +4
Inspired by small intestine motility, we investigate the flow induced by a propagating pendular-wave along the walls of a channel lined with rigid, villi-like microstructures. The…
The slow viscous flow around doubly-periodic arrays of infinite slender cylinders
Lyndon Koens, Rohan Vernekar, Timm Krueger +2
The slow viscous flow through a doubly-periodic array of cylinders does not have an analytical solution. However, as a reduced model for the flow within fibrous porous media, this…
Anisotropic permeability in deterministic lateral displacement arrays
Rohan Vernekar, Timm Krüger, Kevin Loutherback +2
We uncover anisotropic permeability in microfluidic deterministic lateral displacement (DLD) arrays. A DLD array can achieve high-resolution bimodal size-based separation of microp…
Breakdown of deterministic lateral displacement efficiency for non-dilute suspensions: a numerical study
Rohan Vernekar, Timm Krüger
We investigate the effect of particle volume fraction on the efficiency of deterministic lateral displacement (DLD) devices. DLD is a popular passive sorting technique for microflu…
