pre121 - Wind Energy Converters & Fluid Dynamics (Vollständige Modulbeschreibung)

After successful completion of the module students should be able to:

-        Resolve fluid dynamic problems occurring in the field of wind energy converters

-        Measure characteristics of wind energy converters

-        Evaluate wind energy related measurements

-        Interpret such measurements gained in the field of wind energy applications
-        Critically evaluate measured data

This module allows students to access wind energy from the hydrodynamic view angle of the wind resource.
