Analytical investigation and numerical modeling of collisions between a droplet and a fiber

► Energy balance-based calculations allow to predict the scenario of droplet-fiber collision. ► Scenario of collision between droplet and fiber depends on non-dimensional parameters. ► Deposition occurs at low Weber and capillary number - otherwise detachment observed. ► Breakup of a droplet is observed at low impact parameter and high Weber number. ► Two-color lattice-Boltzmann method as an effective tool for droplet-fiber collisions modeling.
