The traditional techniques for wind resource evaluation and the wind park technology were developed for relatively flat terrain. For an effective utilization of wind energy resources in complex terrain the Portuguese case , there is a need for more general tools and computational models, based on the solution of the fluid flow equations in their non-linear original form.
A series of examples will be shown of the results of using computational fluid dynamics techniques, based on either RANS or LES for turbulence modeling of the atmospheric flow over mountainous regions. More recent applications, here based on RANS methodology will focus on the modeling of wind over forested regions. In all cases, computational results will be compared with real field data.
Finally, the use of the current approach, but embedded in a software application for daily forecasting of wind power will also be discussed. Major features of this application will include the coupling of the current code with either weather forecasting models or much simpler statistical models currently used by the wind energy community.
