CFD evaluation analyzes hydraulic efficiency in a bulb turbine, indicating improved performance reliability.

The main aim is to evaluate the performance of a bulb turbine using CFD based on high-resolution 3D scans.
3D scans of the turbine prototype were obtained under controlled conditions.
Key geometric features were processed to create a reverse-engineered model.
Steady RANS simulations were conducted for different head conditions.
Simulations were compared to test results to assess reliability.
Predicted hydraulic efficiencies matched test results within ±3%.
Prototype-based geometry acquisition improved prediction reliability.
The workflow established can be used for future studies on cavitation and optimization.
