Bubble break up in turbulent flows
Laboratoire de Physique de l’école Normale Supérieure, Paris Science Lettres
The transfert of CO2 from the atmosphere to the ocean is estimated to originate at 40% from wave breaking in open seas. Indeed, when a wave breaks, it traps large volumes of air that will fragment and generate submillimetric bubbles. The small bubbles in particular rise slower to the surface, and dissolve faster into the ocean. However, the distribution of bubble size, in particular for submillimetric diameters, remains an open question. In collaboration with L. Deike, we have developed a dual approach, experimental & numerical to identify the physical processes at play in bubble fragmentation. To do so, we inject a controlled volume of air within a turbulent flow, and we track the fragmentation dynamics. Combining experimental & numerical data, I will present how we developed a model to explain the distribution of small bubble size in turbulent flows.
