Francis Turbine Pressure and Velocity Measurements for CFD Validation

Encompassing experimental results from a model Francis turbine, including pressure measurements at selected locations and velocity measurements in the draft tube using Particle Image Velocimetry (PIV). The data covers three operating points: Best Efficiency Point (BEP), part load, and high load. It is intended for defining boundary conditions and validating computational fluid dynamics models.

Use Cases

• Validate computational fluid dynamics models using pressure measurements at selected turbine locations.
• Analyze vortex rope behavior in the draft tube using velocity measurements from Particle Image Velocimetry (PIV).
• Compare turbine performance across three operating points: Best Efficiency Point (BEP), part load, and high load.
• Define boundary conditions for numerical simulations based on experimental pressure and velocity data.

Strengths

• Includes state-of-the-art experimental measurement data from a controlled laboratory environment (Waterpower laboratory, NTNU).
• Covers three distinct and analytically relevant operating points for turbine performance analysis.
• Provides both pressure and velocity data types, enabling multi-physics validation of computational models.

Limitations

• The dataset is specific to a single model Francis turbine, limiting generalizability to other turbine designs.
• Sample size and data granularity (e.g., number of measurement points, time steps) are not specified.
• Data is tied to a specific workshop series (Francis-99 Workshop 1), which may represent a snapshot rather than continuous operation.
