Description
The coalescence of liquid drops is a well-studied and ubiquitous natural phenomenon central to many industrial processes. We study the physics of a granular analogue of this process through the coalescence of particle rafts in which individual particle rearrangements can be directly observed. In the experiments, a pair of two-dimensional bidisperse rafts of microscopic oil droplets are released and coalesce, driven by capillary forces. A tunable cohesive force between particles mediates the large-scale relaxation of the structure. Varying the strength of cohesion, we investigate the geometry and dynamics of this raft coalescence process.
