Shape Optimization of a Tidal Stream Turbine using CAESES and STAR-CCM+
CAESES’ geometry modeling capabilities were used to design the turbine using 19 design variables. This model allowed for automated generation of design variants ready to go for simulation.
Unlike traditional CAD tools, the models were robust and guaranteed high fidelity without the need for manual repair and modification.
CFD Automation and Optimization
These geometries were then coupled to CD-adapco’s STAR-CCM+ to evaluate over 700 designs in an automated loop.
The optimization resulted in a turbine with substantially improved efficiency and torque that was robust over a wide operating range.
Power For Over 400 Homes
The project is now up and running in Paimpol-Bréhat in Brittany, France. It’s the world’s first large-scale tidal energy farm and delivers 8 MW of tidal power for over 4000 homes in the region.
“In our experience, using CAESES for creating parametric models was MUCH faster and easier than with our traditional CAD tool.
With CAESES we can now create all of the design candidates in hours instead of weeks!”
