Planar and curved droplet networks
Duanduan Wan, Mark J. Bowick
TL;DR
This paper investigates how 2D droplet sheets transition from a square to a triangular lattice through impurity seeding or curvature, analyzing the front propagation and reordering processes.
Contribution
It introduces a study of lattice transformation mechanisms in droplet networks induced by impurities and curvature, highlighting the dynamics of front propagation and structural reordering.
Findings
Transformation fronts propagate through the droplet sheet.
Curvature influences the rearrangement process.
Impurity seeding initiates the lattice transition.
Abstract
We study how a two-dimensional square sheet of droplets evolves to the preferred triangular lattice. The rearrangement can be induced either by an impurity seed for flat sheets or by curving the sheet. We analyze the propagation of transformation fronts and the spatial reordering subsequent to the initial perturbation.
