Job description

The energy transition necessitates a substantial expansion of wind energy, requiring a six-fold increase in the current installed wind energy capacity. Many wind turbines cluster to form a wind farm to utilize wind energy more efficiently. The downstream region of a wind turbine, referred to as wake, experiences reduced velocity and increased turbulence intensity. The wake directly decreases the power production and accumulates fatigue damage to wind turbines operating downstream of others in a wind farm. Wind turbine wake causes annual revenue losses of an industry-standard wind farm ranging from 10% to 23%. Wind farm control using wake steering is proposed to minimize the wake effect by maximizing the overall power production and reducing individual wind turbine loads. Implementation of wake steering across existing Dutch offshore wind farms by 2023 is projected to yield potential gains of up to €151 million.

The NWO project “DIAMOND- DynamIc yAw Models fOr wiND turbine/farm design” aims to pave the way for the industrial application of wake-steering-based wind farm control. The project focuses on the spatial and temporal inflow and wake of dynamic yawing wind turbines/farms. It develops new engineering dynamic-inflow and dynamic-wake models that proceeded from a better understanding of the wake dynamics of a dynamic yaw rotor using high-fidelity modelling and wind tunnel tests.

This vacancy focusses on the thorough investigation of wake characteristics of dynamically yawing rotors using analytical, numerical, and experimental approaches. The main research questions includes:

  • What’s the effect of a dynamic yaw rotor on the process of its wake propagation and re-energizing?
  • How to model this dynamic wake effect correctly in the wake model in the engineering design of a wind farm?
  • How does the wake of a dynamic yaw rotor interact with downstream turbines?
  • What are the optimal dynamic yaw settings to maximize the overall power production at a plant level while minimizing loads of individual turbines?

The research will be carried out in close cooperation with the other PhD candidate of the same project, and with national academic and industrial partners working on the NWO-funded project DIAMOND. 


Delft University of Technology (TU Delft)


You should have:

  • A MSc degree in wind energy from a well-established university or an MSc degree in related engineering disciplines such as mechanical engineering, fluid dynamics, applied physics, or applied mathematics with proven experience (courses, projects, and work experience) in the field of wind engineering.
  • A combination of good mathematical and analytical skills and a strong interest in numerical and experimental aerodynamics and are required. Experience with numerical and experimental techniques in aerodynamics or fluid dynamics is preferred.
  • A good command of the English language is required. 

Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis.
