Abstract

The invention relates to a method and device for approximating at least one quantity representative of turbulence in a marine flow by: • determining at least one profile of the marine flow; • selecting at least one eddy type representative of the turbulence, wherein each eddy type comprises at least one eddy size parameter and an eddy strength parameter; • determining a velocity signature and/or a turbulent intensity signature, for each selected eddy type; and • using at least one said determined signature to perform a deconvolution of the profile, in order to determine, for each selected eddy type, at least one probability density function as a function of the at least one size parameter and/or the strength parameter. Furthermore, the invention relates to different methods and devices for controlling the operation of devices adapted to convert kinetic energy of a fluid into electrical energy.
