Call for proposals from companies and consortia interested in undertaking a study on the limits of applicability of different approaches for modelling very large offshore wind farms and clusters, and to understand where risks of systematic biases in far-field wake interactions might appear.
The main objectives of this work are to answer the key research questions below.
- At what wind farm size and/or distance downstream of large wind farms do lower order/idealised models start to differ from higher order models?
- How does wake recovery differ over large distances between idealised and time dependent models, in particular the impact of local wind direction changes?
- How do wake loss predictions differ between time-dependent and statistical approaches?
- How do turbine (e.g., actuator disk) and wind farm (momentum sink block) representations differ in terms of implementation and the comparability/suitability/limitations of modelled downstream wind farm wake?
- What physical mechanisms included in higher-order model and not in engineering models (e.g. Coriolis effect, gravity waves, local wind direction changes) are causing different wake behaviour between the different types of models?
