ABSTRAKT

Vortex identification is a non-consensual point of discussion among fluid mechanics researchers. Classical criteria such as Q and Δ are hereby confronted with a new definition.
A pertinent task for wind power project development studies is the post-processing analysis of the wind resource simulations in order to improve the project design. There is a large interest in extracting more information from typical commercial software − like WindSim, OpenWind, Meteodyn, WAsP − outputs at a minimal cost.
The proposed methodology of vortex identification in flows contributes with a more sophisticated wind resource analysis. It is also interesting to note that the additional financial investment and computational effort to perform this stage's calculations is negligible when compared to the previous calculation steps.
