From meso-scale to micro scale LES modelling: Application by a wake effect study for an offshore wind farm
INNOSEA, P1 rue de la Noë, CS 12102, 44321 Nantes, France
The object of the study is to present the first step of the development of a methodology that aims to merge the gap between meso scale and micro scale modelling. WRF simulations have been carried out in order to consider global wind conditions over a meso scale area of the future wind farm. A statistical analysis of the global wind data over several years has been carried out to initiate the work for the Saint Nazaire site. A focus was made on two wind regimes: the most common wind typical of the site's location and the extreme winds over the period. The WRF results were then used as initial conditions for a micro scale simulation carried out by a non-stationary large-eddy simulation (SOWFA) tool based OpenFOAM solver that computes the flow around 2 turbines. Turbulence statistics were computed and analyzed. Fields of skewness and flatness show found that the distribution of turbulence becomes more homogeneous after the second turbine, while turbulence intensity increases.
