Timber construction is rapidly advancing in structural engineering due to its benefits, such as light weight, ease of prefabrication, and contribution to societal goals. With an increase in building height, however, knowledge garnered by coupling advance modelling and experimental testing will enable …

Dynamic inflow effects occur due to the rapid change of the rotor loading under conditions such as fast pitch steps. The paper presents a setup suitable for the investigation of those effects for non-axisymmetric rotor conditions, namely individual pitch steps. Furthermore, insights into the relevant …

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; …

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 …

In the following thesis, research is conducted on the effect of sea-level rise and expected hydraulic load levels for the Scheldt Estuary, currently and in the future. As climate changes advances and the sea-level rises, insight into the effects of the rise on our coastal area's is essential. Rijkswaterstaat …

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 …

Dynamic stall phenomena bring risk for negative damping and instability in wind turbine blades. It is crucial to model these phenomena accurately to reduce inaccuracies in predicting design driving (fatigue) loads. Inaccuracies in current dynamic stall models may be due to the facts that they are not …

This research proposes new structural lay-outs for large wind turbine blades. The lay-outs were found by an optimisation method where the aerodynamics of wind turbine blades was combined with the structural model of the blade, formulated in a corotational framework. The aeroelastic blade loads were calculated …
