Title:  Lagrangian statistics and particle dispersion in two-dimensional turbulence

Abstract:
A view of turbulence as a multi-scale process of energy transfer helped understanding kinetic energy spectra in Eulerian frame. However to understand mass transport in turbulence one needs to adopt a viewpoint of a particle moving with the flow. Recent developments in laboratory modeling using electromagnetically generated and Faraday-wave driven two-dimensional turbulence highlighted the importance of the externally energized scale, the forcing scale, on single particle dispersion as well as on the pair dispersion. In this talk I will review recent experimental progress on Lagrangian statistics in 2D turbulence.
