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 …

Citizen participation in local renewable energy projects is often promoted as many suppose it to be a panacea for the difficulties that are involved in the energy transition process. Quite evidently, it is not; there is a wide variety of visions, ideologies and interests related to an ‘energy transition’. …

tract Micro wind turbines can be structurally integrated on top of the solid base of noise barriers near highways. A number of performance factors were assessed with holistic experiments in wind tunnel and in the field. The wind turbines underperformed when exposed in yawed flow conditions. The theoretical …

This paper assesses wind resource characteristics and energy yield for micro wind turbines integrated on noise barriers. An experimental set-up with sonic anemometers placed on top of the barrier in reference positions is realized. The effect on wind speed magnitude, inflow angle and turbulence intensity …

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 …

: To have sustainable societies, we need to accelerate the energy transition towards clean energy solutions, however, awareness and understanding of the process is still limited, especially among young people. In addition, the topic has mainly been approached from an engineering angle, ignoring the social …

At the Lunchcolloquim of the TU in Delft Dr. Schepers talked about the International Small Wind Turbine Contest (ISWTC) and the Energy transition centre (Entrance) in Groningen.

In this second guest-lecture at the TU in Delft the point of focus was the technical aspects of wind turbines and extracting energy from wind.

In this guest-lecture several aspects of wind energy were discussed, in particular the present situation in the Netherlands. Additionally the social-economic side of wind energy and technical design were part of the lecture.
