Activity-Driven Dewetting and Rupture in Thin Liquid Films
Preethi M, Daniya Davis, Bhaskar Sen Gupta
Thin-film dewetting is classically governed by an adhesion-mediated spinodal instability in which curvature-driven diffusion controls post-rupture coarsening. We show that internal…
Active alignment-driven coarsening in confined near-critical fluids
Parameshwaran A, Bhaskar Sen Gupta
We investigate vapor-liquid phase separation of an active near critical Lennard-Jones fluid confined within a cylindrical pore using molecular dynamics simulations. Activity is int…
Breaking the Logarithmic Barrier: Activity-Induced Recovery of Phase Separation Dynamics in Confined Geometry
Preethi M, Parameshwaran A, Bhaskar Sen Gupta
Phase separation in confined environments is a fundamental process underlying geological flows, porous filtration, emulsions, and intracellular organization. Yet, how confinement a…
Phase separation and rheology of segregating binary fluid under shear
Daniya Davis, Parameshwaran A, Bhaskar Sen Gupta
We employ molecular dynamics simulation to study the phase separation and rheological properties of a three-dimensional binary liquid mixture with hydrodynamics undergoing simple s…
