Large Eddy Simulation to study wind farm layout effects

This research focuses on simulating the effects of array layout choices on offshore wind farm performance using Large-Eddy Simulation (LES). The code LES code that we have been using is the Software for Offshore/Onshore Wind Farm Applications (SOWFA), developed by the National Renewable Energy Laboratory. The control run is based on the existing offshore wind farm Lillgrund (in Sweden), which includes 48 2.3 MW Siemens wind turbines (hub height 63 m and blade length 46 m). Sensitivity runs were conducted in which the spacing along and across the preveiling wind direction were altered, as well as the alignment of subsequent rows (in line or staggered). The table below shows the first six cases that we have analyzed. Click on an image to see to results of that specific run (WARNING: some links are still under construction).
