1. Assessment of Bordas-Carnot losses in a bulb turbine diffuser using near-field and far-field CFD Models.

2. Versatile low head turbine. (Runner diameter: 1-9m)
1. Bulb Turbine:
Versatile low head turbine. (Runner diameter: 1-9m)
Long establish technology, installed in more than 300 projects.
Operate in the two biggest lagoon project:
La Rance (240MW)
Shiwa Lake (254MW)

3. 2. Ph.D:
Focuses on the study and the analysis of the diffuser.
Main goal of the diffuser is to accelerate the pressure recovery.

4. 3. Work Achieved:
- Worked on the far-field model.
- The complex environment geometry was created using a Fortran program + computed to the Hydro3D software.

5. 3. Future Work:
Preparation of a physical model to validate the results of the CFD models.
Implementation of cross-currents and tide series into the Hydro3D models.
CFD testing on different diffusers to optimise its design.
