Abstract

We discuss a couple of ‘in silico’ experiments discussing ‘hard-wired’ policies to force and control turbulent fluctuations using Lagrangian protocols for the case of Homogeneous and Isotropic Turbulence in 3d (by acting on strong vorticity events [1]) and 2d Rayleigh Benard convection (by acting on the heat injection [2]). Potential applications towards active smart control of turbulence are also discussed.  This project has received funding from the European Union’s Horizon 2020 research and innovation programme under Marie Sklodowska-Curie Grant Agreement No. 765048, and by the European Research Council (ERC) under the European Union’s Horizon 2020 research and innovation programme (Grant Agreement No. 882340).   Properties of Turbulence in the Presence of a Smart Small-Scale Control. M. Buzzicotti, L. Biferale, and F. Toschi. Phys.
