This PhD position (Early Stage Researcher, ESR 5) will be funded by the zEPHYR (Towards a more efficient exploitation of on-shore and urban wind energy resources) ETN of the European Commission (H2020-MSCA-ITN-2019). This ETN is focused on the development of performant wind farms by addressing simultaneously the individual performance of each turbine composing the wind farm and the efficient harvesting of the local wind resources in on-shore and urban environments. Researchers recruited in zEPHYR will investigate emerging technologies through laboratory experiments, theoretical modelling and numerical simulations, addressing the following aspects: mesoscale and microscale atmospheric boundary layer simulations, rotor aerodynamics, aeroacoustics and structural dynamics, atmospheric propagation and human factors, uncertainty quantification, sensitivity analysis and multi-physics optimization. A total of 15 PhD positions are available at 8 Universities, 1 Research Center and 4 Industries.

ESR5, associated with the Parallel CFD & Optimization Unit (PCOpt) of the School of Mechanical Engineering of the National Technical University of Athens (NTUA) will perform adjoint- and evolutionary algorithm-based shape-optimization of the rotors of ~5kW HAWTs, roof- or ground-mounted, installed in an urban environment; aerodynamic and aeroacoustic optimization will be based on mesoscale simulations, by also considering wind data and roughness uncertainties. Her/his work (and PhD thesis) will be based on the shape optimization methods that have been developed in the PCOpt/NTUA; these include the OpenFOAM based CFD analysis & adjoint solvers (the publicly available, in v1906, adjointOptimisationFOAM), a shape optimization workflow, other in-house CFD solvers, geometry parameterization tools, the optimization platform EASY (the Evolutionary Algorithm SYstem, see: http://147.102.55.162/EASY/) and methods for optimization in an uncertain environment. The first goal of the ESR is to set-up a new optimization workflow for roof- and ground-mounted HAWTs in the built-environment by combining (adapting/upgrading, if needed) the aforementioned tools and, after the necessary validation tests as well as the collection of the necessary data, proceed to the design-optimization of the rotors of ~5kW HAWTs, roof- or ground-mounted, installed in an urban environment. The availability of more than one tool for almost all constituents of this workflow maximizes flexibility and may become useful for verification purposes. Then, the optimization will account also for noise reduction (using hybrid approaches) and, also, wind data and roughness uncertainties using the available Stochastic Collocation Uncertainty Quantification method.

Planned secondments: at the Universiteit Twente, the Siemens Industry Software NV, Instytut Maszyn Przeplywowych Im Roberta Szewalskiego Polskiej Akademii, and Valeo Systemes Thermiques. (~5 months overall).

Benefits

The multidisciplinary topics addressed in zEPHYR are scientifically challenging and of high technological and economical relevance, promising interesting career perspectives in academic and multi-sectorial industrial environments.

Competitive salary plus allowances (included in the ITN package; of which, taxes, social/pension contributions have to be paid): Living, Mobility and Family Allowances. More information on the ITN financial support available on the EU website. 36-month contract

Eligibility criteria

The zEPHYR partners do strictly adhere to the ethical standards of the European Charter for Researchers and Code of Conduct for the Recruitment of Researchers. Female scientists are particularly encouraged to apply. Applicants must satisfy some eligibility rules, in particular in terms of transnational mobility. A strict equal opportunity, gender-neutral and internationally comparable recruitment procedure is implemented.

Selection process

Based on upon requirements and the Code of Conduct for the Recruitment of Researchers.
