To win, a model must thin: Capillary thinning as a benchmark complex flow for constitutive models of viscoelastic polymer solutions
Ranganathan Prabhakar, Joseph P. Connell
Capillary thinning of a liquid bridge is an exemplar of complex flow, where the macroscopic geometry couples tightly to the microscopic evolution of polymer conformations. Since it…
Cluster and conquer: The morphodynamics of invasion of a compliant substrate by active rods
Mohammad Imaran, Mandar Inamdar, Ranganathan Prabhakar +1
The colonisation of a soft passive material by motile cells such as bacteria is common in biology. The resulting colonies of the invading cells are often observed to exhibit intric…
Linear stability of an active fluid interface
Amarender Nagilla, Ranganathan Prabhakar, Sameer Jadhav
Motivated by studies suggesting that the patterns exhibited by the collectively expanding fronts of thin cells during the closing of a wound [Mark et al., Biophys. J., 98:361-370,…
Effect of stretching-induced changes in hydrodynamic screening on coil-stretch hysteresis of unentangled polymer solutions
Ranganathan Prabhakar, Chandi Sasmal, Duc At Nguyen +2
Extensional rheometry and Brownian Dynamics simulations of flexible polymer solutions confirm predictions based on blob concepts that coil--stretch hysteresis in extensional flows…
Extensional viscosity of copper nanowire suspensions in an aqueous polymer solution
Amarin G. McDonnell, Naveen N. Jason, Leslie Y. Yeo +3
Suspensions of copper nanowires are emerging as new electronic inks for next-generation flexible electronics. Using a novel surface acoustic wave driven extensional flow technique…
Significance of thermal fluctuations and hydrodynamic interactions in receptor-ligand mediated adhesive dynamics of a spherical particle in wall bound shear flow
K. V. Ramesh, R. Thaokar, J. Ravi Prakash +1
The dynamics of adhesion of a spherical micro-particle to a ligand-coated wall, in shear flow, is studied using a Langevin equation that accounts for thermal fluctuations, hydrodyn…
Enhancement of coil--stretch hysteresis by self-concentration in extensional flows, and its implications for capillary thinning of liquid bridges of dilute polymer solutions
Ranganathan Prabhakar
The coil-stretch transition in extensional flows of viscoelastic dilute polymer solutions is known to be associated with a strong hysteresis in molecular conformations and rheo-opt…
Enhancement of coil-stretch hysteresis by self-concentration in polymer solutions
Ranganathan Prabhakar
The effect of concentration on coil-stretch hysteresis in extensional flows of polymer solutions is examined with insights from Brownian dynamics simulations of isolated chains and…
Gaussian approximation for finitely extensible bead-spring chains with hydrodynamic interaction
R. Prabhakar, J. Ravi Prakash
The Gaussian Approximation, proposed originally by Ottinger [J. Chem. Phys., 90 (1) : 463-473, 1989] to account for the influence of fluctuations in hydrodynamic interactions in Ro…
