ForWind – Center for Wind Energy Research has a vacant PostDoc position in the research group “Wind Energy Systems” at the Institute of Physics of the Carl von Ossietzky University of Oldenburg starting as soon as possible for a limited period of 3 years for a
PostDoc position (f/m/d) (Salary according to TV-L E13, 100%) Large-eddy simulations of wind turbines’ response and challenging atmospheric conditions
The interactions between closely spaced wind turbines and between turbines and particular atmospheric flow phenomena are complex. Atmospheric large-eddy simulations (LES) are dedicated to enhancing their understanding. Driving LES with information obtained from mesoscale atmospheric simulations is regarded as a possibility to reproduce observed atmospheric situations in a simulation environment. Aeroelastic simulations coupled to the LES allow for the simulation of wind turbines’ response under such conditions. The results of high-fidelity simulations support the development of cheaper tools that the industry can apply.
Job Description
Your main objective is to improve the numerical modelling of the dynamic response of a utility-scale wind turbine in the near wake of another turbine and on particular meteorological conditions. You will employ a coupling between the large-eddy simulation (LES) model PALM and the aeroelastic code OpenFAST to analyse the flow conditions and system dynamics. You will compare your results with the project partners’ open-field measurements and computational fluid dynamics data.
Among others, your tasks will comprise:
• implementation of a new turbulence generator to tailor the LES inflow to measured flow conditions,
• analysing a unique set of meteorological and wind turbine data to derive LES validation cases,
• applying LES driven by mesoscale simulations to other challenging meteorological conditions (e.g. low-level jets, wind gusts),
• enhancing the aeroelastic modelling in the coupled LES simulations.
Job offer
We offer you the opportunity to develop your scientific career in a young and lively academic environment. You will be working in the WindLab – one of the university’s most modern office and lab spaces – and have the opportunity to do flexible and mobile work. Your pathway as a researcher is actively supported by, e.g.,
• multidisciplinary cooperation with other researchers at ForWind and Fraunhofer IWES in Oldenburg,
• direct collaboration with industry while maintaining the links with our national and international partners in academia,
• optional secondment at an international research institute
• development of personal, scientific, and teaching skills through an individual training programme and selected teaching tasks,
• opportunities to present scientific results at international conferences and through peer-reviewed publications to extend your specific network,
• active participation in the planning and implementation of teaching and supervision of PhD students
• contributing to the conceptualisation, application and organisation of third-party funded projects.
The payment is based on the collective agreement for the public service in the German federal states, TV-L E13, for a 100% position.
For your work, you will have access to our high-performance computing systems installed in 2023 and a regional HPC cluster that allows for performing cutting-edge simulations. You will work in a team with over two decades of experience in numerical fluid dynamics and simulations of atmospheric flows using the mesoscale model WRF and the LES model PALM. You can access measurement data from a worldwide unique research wind farm for validation purposes.
Requirements for employment include:
• PhD degree in physical or engineering sciences,
• university degree (diploma or master) in Physical Sciences, Meteorology, Mechanical or Aerospace Engineering, Renewable Energy (with a major in wind energy) or in a similar field,
• profound knowledge in computational fluid dynamics and either aerodynamics (especially aeroelasticity) or atmospheric sciences,
• experience in analysing large data sets,
• fluency in communicating and reporting in English.
Desired (but not mandatory) qualifications are:
• experience in atmospheric large-eddy simulations,
• experience in structural dynamics of mechanical systems,
• experience abroad of several months during the school, graduation period or employment after graduation,
• good German skills.
