Job description

Do you have experience in computational fluid dynamics, machine learning, and offshore wind farm flow modeling and wish to contribute to the development of wind energy? Then we are searching for you to help us create digital solutions for future offshore wind technology.

The Faculty of Science and Technology at the Norwegian University of Life Sciences (NMBU) has a vacant PhD–position related to computational fluid dynamics, machine learning and offshore wind energy. The PhD position is for a period of 3 years, or up to 4 years if teaching and other work duties are agreed.

Global wind power is expected to grow three times over the next decade to avoid the worst impact of climate change. The wind power plants are constructed with turbines having large rotor diameters to allow maximum energy yield from the oncoming wind. Special attention is given to reducing the cost of energy and increasing profitability, and this is anticipated to be achieved by developing optimized design, analysis, prediction, and monitoring tools capable of simulating aerodynamic flows accurately in offshore wind farms. To this end, traditional analytical tools employed to model aerodynamic flows in a wind farm are fast but include simplifications that can compromise the overall integrity of solutions. On the other hand, high-fidelity flow models based on computational fluid dynamics (CFD) are more accurate but at the same time require significantly high computational resources to obtain meaningful results. 

The Ph.D. project aims to conduct research and innovation in flow simulation in offshore wind turbines by combining high-fidelity computational fluid dynamics (CFD) models with machine learning (ML) models. The developed state-of-the-art models are expected to be integrated into future digital twin technology to fulfill the industrial needs of computationally efficient tools and form a basis for condition monitoring, prediction, analysis, and maintenance of offshore wind turbines. Key research areas that will be exploited in the Ph.D. research project will be physics-based and data-driven Reduced Order Models (ROM) to simulate and predict wind farm flows, especially in the wake region.

An application for a PhD position at NMBU is at the same time an application for admission to a PhD programme at the institution. The documentation that is necessary to ensure that the admission requirements are met must be uploaded as an attachment.

Main tasks

The objective of the Ph.D. is to

  • Carry out research on high fidelity simulation, physics-based and data-driven models for modeling and simulation of offshore wind turbines.
  • Take part in the mandatory PhD research education program.
  • Conduct independent research and publish in recognized scientific journals and conference proceedings.

The above may require conducting high fidelity simulations using computational fluid dynamics (RANS, LES) in OpenFOAM etc. on supercomputing infrastructures, development of methods based on Reduced Order Model (ROM) techniques with integration to machine learning and artificial intelligence methods (feed-forward networks, Artificial Neural Networks (ANN), etc.)

The position reports to Associate Professor M. Salman Siddiqui and the department head. Close collaboration is expected with Associate Professor Fadi Al Machot of data science department at NMBU, and other relevant research groups in Europe and China.

The successful candidate is expected to enter a plan for the progress of the work towards a PhD degree during the first months of the appointment, with a view to completing a doctorate within the PhD scholarship period.
