Deformation-induced spectral softening drives phase separation on non-spherical membranes
Avraham Moriel, Howard A. Stone
Models of curvature-driven membrane sorting couple composition directly to membrane bending elasticity. Here we show that shape deformations can destabilize a homogeneous state wit…
The effects of surfactant solubility on inertial Marangoni flow: theory and numerics
Jun Eshima, Luc Deike, Howard A. Stone
Surface active agents (surfactants) are common contaminants found on most air-liquid interfaces. Surfactants lower the surface tension, and hence surfactant concentration gradients…
Expansion of a hole in a viscoelastic liquid sheet
Tachin Ruangkriengsin, Rodolfo Brandão, Howard A. Stone
Experiments on highly viscous polymeric films show that punctured holes expand exponentially in time, without sustained accumulation of liquid near the rim. This response departs f…
Understanding the Theory--Experiment Discrepancy in Pressure Drop of Dilute Polymer Solutions in Channel Flows
Nan Hu, Jonghyun Hwang, Evgeniy Boyko +1
For decades researchers have experimentally observed that the flow of dilute viscoelastic polymer solutions through contraction or contraction--expansion channels yields results at…
Nonlinear diffusion and compressive rims in source-driven biopolymer condensates
Avraham Moriel, Howard A. Stone
Many subcellular condensates continuously produce biopolymers. Coupling Flory-Huggins thermodynamics to two-fluid viscoelasticity, we probe the diffusion of such source-driven poly…
Polymer-polymer interdiffusion: effects of entanglements and a polymeric source
Avraham Moriel, Howard A. Stone
Many industrial applications and biological scenarios involve the interdiffusion of two polymeric species. Motivated by biological subcellular source-driven processes, we study pol…
Enucleated incompressible red blood cells in shear flow: theoretical analysis of shape instabilities
Avraham Moriel, Howard A. Stone, Simon Mendez
Red blood cells (RBCs) are essential for oxygen transport, and their remarkable ability to undergo significant deformations during flow is a crucial feature for their physiological…
Solubility enhanced surfactant-induced flow in air-liquid-air sheets
Jun Eshima, Tristan Aurégan, Emmanuel Villermaux +2
Liquid interfaces appear throughout nature and engineering and are typically contaminated by surface active agents (surfactants), which are characterized by a wide range of solubil…
