Abstract

The following article will validate the results obtained using the actuator disc method in the state of the art numerical Computational Fluid Dynamic (CFD) tool WindSim using on-site measurements from the offshore wind farm Lillgrund. WindSim solves the mass, momentum and energy conservation equations using the Reynolds Average Navier Stokes (RANS) method. Emphasis will be put here on investigating how the choice of different parameters influences the results, and comparisons will be performed with experimental data. The quantity that will be compared is the individual energy production of the wind turbines for different grid resolutions, inflow angles, thrust radial distributions and turbulence closure models.
