Overview

This study demonstrates how gas flow dynamics influence droplet size distribution in thin liquid films, indicating the role of instabilities.

Key Points

  • Breakup behavior of thin liquid sheets is influenced by gas phase instabilities and vortical structures.
  • At Reg=300, rim and Rayleigh–Plateau-type instabilities cause breakup, while hole formation dominates at higher Reynolds numbers.
  • Numerical simulations reveal that gas-induced instabilities lead to variations in droplet size distribution.
  • The application of a manifold death algorithm enhances the robustness of simulations against numerical artifacts.
