Experimental Data on Free-Surface Turbulence with FTP and PIV Measurements

Simultaneous surface elevation and sub-surface velocity field measurements from a controlled tank experiment. The data comprises two forcing regimes (Case A and Case B) and includes measurements at four horizontal depths beneath the water surface. Processed results are stored in NetCDF and tabulated text files, supporting the journal article by Babiker, Omer.

Use Cases

• Validate computational fluid dynamics (CFD) models of turbulence based on the described experimental forcing regimes.
• Study correlations between free-surface features and sub-surface turbulence structures using the simultaneous FTP and PIV measurements.
• Analyze the impact of different forcing intensities (Case A vs. Case B) on near-surface flow dynamics.

Strengths

• Contains paired, simultaneous measurements of surface elevation (FTP) and velocity fields (PIV), enabling correlation studies.
• Includes data for two distinct forcing regimes (Case A and Case B) and four horizontal depths, allowing for comparative analysis.
• Data is processed and stored in structured binary (NetCDF) and tabulated text formats, with a provided sample code for loading.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and overall dataset size are unknown, which may limit suitability assessment.
• Data is derived from a specific laboratory setup; generalizability to other scales or environments may be limited.
