Context

Centrale Nantes has a new PhD position available within the framework of the EU-funded FLOAWER project. FLOAWER project main goal is to train 13 early stage researchers (ESRs) to design better performing, economically viable floating wind turbines.

Among these ESRs, Centrale Nantes has one about the hydrodynamic analysis and numerical modelling of heave-plates dedicated to the design of floating WT.

Heave plates are commonly used in floating wind energy for shifting the resonance periods of the platform out of the predominant wave periods and for damping the motion of the whole structure. During the design phases, heave plates are generally modelled in engineering design tools through Morison-type empirical formulations. These formulations are based on hydrodynamic coefficients that strongly depend on the flow properties (Keulegan–Carpenter number, Reynolds number) and are generally determined experimentally. Several hydrodynamic database are publically available that provides data for different shapes and flow properties but come from a literature dedicated to classical offshore engineering with structures relatively different to the ones developed in the FOW community (larger diameter of heave plates, larger amplitudes of motion, position wrt the free surface).

Objectives

One of the objectives therefore lies in the implementation of a new methodology based on both CFD calculations and wave tank tests for obtaining a comprehensive hydrodynamic database dedicated to the floating wind community. Wave tank tests and simulations will be carried out for various geometry, column-diameter/heave-plate diameter ratio and heave-plate depth. Experimental tests will be conducted in ECN 3D-wave tank with realistic design and operation sea-states. The PhD student will participate to the design, setup, experimental campaign, and result analysis. Numerical tests will be conducted with an in-house variant of OpenFOAM dedicated to wave-structure interaction through the coupling with accurate deterministic wave evolution models. The PhD student will setup, run and analyze the different cases, including some specific numerical developments if needed.

A second objective will be the characterization of the validation domain of state-of-the-art engineering models for modelling heave-plates and their improvement through a model derived from the experimental and numerical study.

Expected Results

  • Hydrodynamic database for various geometries (column-diameter/heave-plate diameter ratio and heave-plate depth…)
  • Improved numerical engineering models for modelling heave-plates.

Planned secondment(s)

Secondments are planned for all ESRs of FLOAWER project. For the present PhD position, the student will have to spend 3 months during the first year at NTNU in Norway (supervisor Erin Bachynski), to learn on on the design and the experimental testing of heave-plates. At the end of the 2nd year, the student will spend 3 month at IDEOL in La Ciotat (supervisor Riccardo Mariani) to work on a study case on the modelling of heave-plates for barge-like foundation.

 

Benefits

 

  • Salary: The successful candidates will be employed on a full-time basis

    with a competitive salary in accordance with the MSCA rules and the

    personal circumstances of the applicant. The successful candidate will

    receive a financial package consisting of MSCA living allowance and

    mobility allowance. Eligible applicants with a family will also receive

    an additional family allowance according to the rules of the MSCA. The

    exact (net) salary will be confirmed upon appointment and will depend on

    a Host Institution's local tax regulations.

 

  • Supervision: ESRs will benefit from joint

    supervision and multi-sectoral advisory committees, ensuring the

    successful completion of their Individual Research projects.

 

  • Training: In addition to their individual scientific projects ESRs will be collaborating with world leading research groups

    within the Consortium through secondments. All ESRs will benefit from

    extensive and varied further continuing education, completing a series

    of carefully designed training modules and transferable skills courses;

    they will participate in symposia, workshops and international

    conferences and will have meaningful exposure to the industrial

    environment through FLOAWER industrial partners.

Eligibility criteria

Applicants need to fully respect three eligibility criteria[1] (to be demonstrated in the CV):

 

  1. At the core of the MSCA-ITNs is researcher mobility. At the time

    of commencing their FLOAWER employment, researchers must not have

    resided or carried out their main activity (work, studies, etc.) in the

    country of their (recruiting) host organisation for more than 12 months

    in the 3 years immediately prior to their recruitment. Short stays, such

    as holidays, are not taken into account

  2. Applicants must at the first day of their FLOAWER employment contract, be in the first four years (full-time equivalent research experience) of their research career and have not been awarded a doctoral degree. This research experience is measured FROM

    the date when they obtain the degree which formally entitles them to

    embark on a doctorate (either in the country in which the degree was

    obtained or in the country in which the researcher is recruited, even if

    a doctorate was never started or envisaged). Research Experience is

    measured TO the first day of the FLOAWER employment contract of the researcher.

  3. English language proficiency: ESRs must demonstrate

    proficiency in both written and spoken English. This is mandatory for

    the ESRs to take full advantage of the training program.

 

  1. [1] Usual MSCA Eligibility Criteria apply and will be verified during the application process. For more information on MSCA, please see : http://ec.europa.eu/mariecurieactions.

 

Selection process

All applicants must send a CV and cover letter to: contact-floawer@ec-nantes.fr or jean-christophe.gilloteaux@ec-nantes.fr

A recruitment committee will evaluate the applications and contact the selected applicants for a teleconference interview.
