<p>A method for approximating or modelling turbulence in a fluid flow e.g. for a marine or wind turbine comprises: determining at least one profile of the 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 the signature(s) to perform a deconvolution of the profile, in order to determine, for each selected eddy type, a probability density function as a function of the size and/or strength parameters. This method may be used in a unit for controlling or designing turbines such as marine turbines. The use of simplified eddy profiles improves computational efficiency.</p> |
