MARTINOVICH, C.; ZALDUENDO, I.  e  COBELLI, P.. CLUSTERING OF LAGRANGIAN PARTICLES IN 2D TURBULENCE. An. AFA [online]. 2023, vol.34, n.4, pp.5-5. ISSN 0327-358X.  http://dx.doi.org/10.31527/analesafa.2023.34.4.103.

In this paper we design and construct an experiment to generate and study 2D turbulence. We calculate velocity and vorticity fields, the energy spectrum and Bondarenko’s parameter for the system both in decay and onset; those values resultin aD = (-0.400 ±0.012) s-1 and aE = (0.404±0.005) s-1,respectively. Additionally, we study the distribution of particles in the flux through the use of Voronoi tesselations.
