Experimental study of the mutual interactions between waves and tailored turbulence

A novel experiment on interactions between waves and turbulence using our water channel with a current tailored by an active grid.

Vortex imprints on a free surface as proxy for surface divergence

We develop a computer vision method to identify surface imprints of attached vortices in turbulence under a free surface and show how these might be used as a proxy for flux of gas and heat between water and air, a possible method for remote sensing.
