Influence of surfactant concentration on drop production by bubble bursting
Juliette Pierre, Mathis Poujol, Thomas Séon
Abstract
Sea spray plays a key role in moisture fluxes between the atmosphere and the ocean. These aerosol particles are mostly formed by the drops ejected by bursting bubbles at the air-sea interface.The mechanisms underlying the drops production from a bursting bubble event have therefore been intensively studied, however, despite the diversity of the surface-active agents present in the oceans, their influence has been overlooked. In this paper, we show experimentally that the role of water contamination by surfactant molecules can be astonishing and needs to be considered to improve the prediction of the sea spray characteristics.
