Collection of aerosol particles by falling deformable drops
The animations visualize numerical simulations of a water drop freely falling through air laden with solid particles for various Reynolds and Weber numbers. The liquid–gas interface is tracked using a coupled Volume of Fluid and Level Set method, capturing drop shape, deformation, and oscillations ranging from nearly spherical to deformed regimes.The surrounding airflow is shown using velocity contours, highlighting wake formation and unsteady flow structures that intensify with increasing Reynolds number. Solid particles are represented as Lagrangian points, with trajectories governed by drag, gravity, and Brownian motion.The animations illustrate particle deflection, wake entrainment, and capture on the drop surface. They provide visual insight into the coupling between drop deformation, flow unsteadiness, and particle capture mechanisms.
