The course describes the aerodynamic phenomena involved in wind energy, an energy source that is strategic in the transition from a reliance on fossil fuels to renewable energy to address the challenges of energy security and climate change. The performance of wind turbines are first described according to momentum-based theories providing a detailed characterisation of the wind-turbine blade aerodynamics and guidelines about its optimisation. Elements of meteorology and wind-resource assessment are introduced to learn what is causing the wind and how it is affected by large-scale dynamics down to the local terrain conditions. Current measurements techniques and corrections are presented for both wind-tunnel and atmospheric measurements. Elements of flow modelling and wind-resource assessment are provided together with guidelines about the design of wind farms both in classrooms and by means of dedicated software suites used in the wind-energy community.

Intended learning outcomes
Once the course will be completed, the student should be able to:
- Explain main concepts of wind energy and how wind turbines work from an aerodynamic perspective.
- Explain the momentum theory and derive Betz and Glauert rules.
- Design an optimum blade using blade-element momentum theory.
- Describe available fluid-mechanics measurement methods related to wind energy and under which conditions they are applicable.
- What are wind turbine real operating conditions inside the atmospheric boundary layer and the consequent effects on the wind turbine loads.
- Explain basic meteorological forces and how the affect global and local winds.
- Describe the daily and seasonal variations of the atmospheric boundary layer both on land and for offshore conditions.
- Use different simulation methods for wind energy production estimations and when they are applicable and what limitations they have during different terrain conditions.
