The Institute and the recruiting departement
French Research Institute for Exploitation of the Sea, Ifremer, through its research work and expert advice, contributes to knowledge of the oceans and their resources, to monitoring of marine and coastal environments and to the sustainable development of marine activities. To these ends, Ifremer conceives and operates tools for observation, experimentation and monitoring, and manage the oceanographic databases.
Created in 1984, Ifremer is a French public institute of an industrial and commercial nature. It is supervised jointly by the Ministry of Higher Education and Research and the Ministry of the Environment, Energy and Marine Affairs.
Ifremer undertakes research missions, offers expert advice and acts as a funding agency.
Ifremer performs targeted applied research to address the questions posed by society (climate change effects, marine biodiversity, pollution prevention, seafood quality etc.). Results include scientific knowledge, technological innovations, and systems for ocean observation and exploration. Partnerships may be public, private or a combination of the two.
Ifremer works in a network with the French scientific community, also collaborating with international partner organizations, in the frame of several national and international projects, including contractual activities.
General areas of responsibility (principal missions)
The recent development of Floating Offshore Wind Turbine (FOWT) opens the path for technologies of wind turbine rotors that have been put aside by the massive development of horizontal axis wind turbine (HAWT) due to their advantages in bottom fixed application. The challenge of this project is to both test numerically and experimentally the different rotor’s designs, designed for horizontal axis (HAWT) or vertical axis (VAWT) and to compare their performances on the same floater.
L’IFREMER, in collaboration with the LEGI Lab (UMR5519) in Grenoble, is developping a new concept of VAWT dedicated to the FOWT WindQuest, supported by the company HydroQuest.
A first experimental campaign performed at Ifremer Wave&Wind tank in Brest has validated the theoretical advantages of VAWT versus HAWT, advantages being low centers of gravity and thrust. A second campaign in wind tunnel focused on the influence of the motion of the floater on the aero performances and loads of a VAWT are planned in 2020. In the wind tunnel, the motions of the floater will be simulated by actuators. Eventually, the test of a 1:10 scale demonstrator in Ste Anne testing site is planned at the end of the project, where the FOWT will be subject to real sea states and wind.
Simulation codes coupling the hydro response of the structure with the aero performance of the rotor have been developed for HAWT (FAST –HydroDyn) but are still work in progress for VAWT (CACTUS – ECNInnosea).
The main goal of this postdoctoral position is to develop tools dedicated to VAWT to simulate the aerodynamic and hydrodynamic behavior of a FOWT with a vertical axis rotor. Two complementary approaches could be developed in this 18month position:
Results of the simulation will be compared with the experimental results from the wave tank and the wind tunnel.
