Active sorting to boundaries in active nematic -- passive isotropic fluid mixtures
Saraswat Bhattacharyya, Julia M. Yeomans
We use a two-fluid model to study a confined mixture of an active nematic fluid and a passive isotropic fluid. We find that an extensile active fluid preferentially accumulates at…
Phase Ordering in Binary Mixtures of Active Nematic Fluids
Saraswat Bhattacharyya, Julia M. Yeomans
We use a continuum, two-fluid approach to study a mixture of two active nematic fluids. Even in the absence of thermodynamically-driven ordering, for mixtures of different activiti…
Viscoelastic confinement induces periodic flow reversals in active nematics
Francesco Mori, Saraswat Bhattacharyya, Julia M. Yeomans +1
We use linear stability analysis and hybrid lattice Boltzmann simulations to study the dynamical behaviour of an active nematic confined in a channel made of viscoelastic material.…
Phase Separation Driven by Active Flows
Saraswat Bhattacharyya, Julia M. Yeomans
We extend the continuum theories of active nematohydrodynamics to model a two-fluid mixture with separate velocity fields for each fluid component, coupled through a viscous drag.…
Coupling Turing stripes to active flows
Saraswat Bhattacharyya, Julia M. Yeomans
We numerically solve the active nematohydrodynamic equations of motion, coupled to a Turing reaction-diffusion model, to study the effect of active nematic flow on the stripe patte…
