Research

Generation of energy and vorticity production by surface waves through two-dimensional turbulence

 

The energy transfer process in quasi-2D turbulent flows that develop on the surface of Faraday waves is investigated with laser techniques such as Particle Image Velocimetry and Particle Tracking Velocimetry.

Additionally, the interactions of the surface layer with the flow beneath the surface are studied: how does the vertical movement of the waves generate vorticity in the horizontal plane? What kind of velocity profiles and flow structures develop below the surface?"
