THYMOTE

Tidal turbulence: modelling, field observations and tank experiments

Duration: 36 months (2016 - 2019)

Context

Tidal sites are, by definition, places where the strongest tidal currents are found. They usually flow over complex rocky bathymetries that generate intense turbulent motions. To understand the turbulent nature of this flow is critical for maximising tidal turbine yield and minimising structural fatigue. Development of the tidal energy industry would benefit from improved knowledge of turbulent flow properties.

Objective

To combine measurements and numerical development to obtain high resolution information on the turbulent flow of tidal sites.

Main achievements

  • In-situ measurements of currents flowing over rocky seabeds with complex bathymetry and generating intense turbulent movements.
  • Tank tests.
  • Development of numerical codes.

Conclusion

THYMOTE has led to the development of numerical tools to better apprehend the turbulent processes present on tidal sites. The calculation tools developed in association with the resources of France Energies Marines are now available to support the players in the tidal turbine sector in the fine characterisation of turbulence on sites of interest for the deployment of tidal turbine systems
