Short summary
This study uses advanced computer simulations to explore how falling water drops remove airborne particles. It shows that, when drops deform and oscillate, their motion strongly affects how efficiently aerosols are captured. The model accurately predicts drop speed and shape, but capture rates can differ from experiments by up to an order of magnitude. These gaps likely stem from missing physical effects (evaporation), uncertainties in aerosol measurements, and numerical inaccuracies.
