Spatiotemporal rheochaos in nematic hydrodynamics
Buddhapriya Chakrabarti, Moumita Das, Chandan Dasgupta +2
Motivated by the observation of rheochaos in sheared wormlike micelles [Bandyopadhyay et al., Phys. Rev. Lett, 84 2022, (2000); Europhys. Lett. 56, 447 (2001); Pramana 53, 223 (199…
The segregation instability of a sheared suspension film
Rama Govindarajan, Prabhu R. Nott, Sriram Ramaswamy
Starting from the equations of Stokes flow and the mass conservation of particles as determined by shear-induced diffusion, we derive the coupled equations for the dynamics of part…
Rheology of Active-Particle Suspensions
Yashodhan Hatwalne, Sriram Ramaswamy, Madan Rao +1
We study the interplay of activity, order and flow through a set of coarse-grained equations governing the hydrodynamic velocity, concentration and stress fields in a suspension of…
Collective stochastic resonance in shear-induced melting of sliding bilayers
Moumita Das, G. Ananthakrishna, Sriram Ramaswamy
The far-from-equilibrium dynamics of two crystalline two-dimensional monolayers driven past each other is studied using Brownian dynamics simulations. While at very high and low dr…
