High fidelity numerical simulations of breaking waves: transition to turbulence, drops and bubbles formation.

Breaking waves modulate exchange of mass between the ocean and the atmosphere by entraining air bubbles and ejecting sea spray droplets. 
I will present some recent efforts in developing high fidelity numerical simulations of breaking waves at high Reynolds number, able to resolve 
a wide range of scales, including accurate resolution of drops and bubbles formation [1]. I will also discuss configurations on related processes, 
including sea spray generation by bubble bursting [2], bubble deformation and break-up in turbulence [3] and mass transfer in two-phase flows. 
The work leverages the open-source library Basilisk and its adaptive mesh refinement and momentum conserving scheme.
