The dynamic inflow effect describes the unsteady aerodynamic response to fast changes in rotor loading due to the inertia of the wake. Fast changes in turbine loading due to pitch actuation or rotor speed transients lead to load overshoots. The phenomenon is suspected to be also relevant for gust situations; …

Presentation for the Distributed Wind Summer 21 meeting of Task 41 of the International Energy Agency Wind Technology Collaboration Platform (IEA Wind TCP)

In this presentation a new EA Wind Task is presented, i.e. an international cooperative project on the field of aerodynamic wind turbine measurements organised under auspices of the IEA

Ook deze keer gaan we online, het is niet anders! Na een aantal interessante en ook gezellige ‘echte’ bijeenkomsten moesten we immers vanaf maart 2020 online verder.Met de bijeenkomsten en de Webinars hebben we geprobeerd jullie zoveel mogelijk te laten zien wat de sector te bieden heeft en wat het tot …

Wind turbines are usually clustered in wind farms which causes the downstream turbines to operate in the turbulent wakes of upstream turbines. As turbulence is directly related to increased fatigue loads, knowledge of the turbulence in the wake and its evolution are important. Therefore, the main objective …

Dynamic stall phenomena carry the risk of negative damping and instability in wind turbine blades. It is crucial to model these phenomena accurately to reduce inaccuracies in predicting design driving (fatigue and extreme) loads. Some of the inaccuracies in current dynamic stall models may be due to …
