Large eddy simulations analyze turbulent flow in partially-filled pipes, focusing on secondary currents' impact on wall pressure and turbulence structures. The dataset includes JPEG and MP4 files totaling 13.3 MB, authored by Yan Liu and last updated on 2026-05-14. It is shared under a CC-BY-4.0 license on figshare.
Use Cases
- Analyzing the structure and meandering pattern of secondary currents based on the described symmetric vortices and streamwise wavelength.
- Studying the correlation between wall pressure fluctuations and turbulence events like sweeps and ejections based on the two-point correlation analysis mentioned.
- Investigating the disruption of very-large-scale motions in partially-filled pipes based on the described inhibition by secondary currents.
- Modeling non-uniform pressure fluctuations along the pipe perimeter based on the described influence of secondary current direction.
Strengths
- Data is derived from large eddy simulations, a high-fidelity computational fluid dynamics method.
- Includes visual outputs in JPEG and MP4 formats, which can aid in qualitative analysis of flow structures.
- Shared under a permissive CC-BY-4.0 license, allowing for wide reuse and adaptation.
Limitations
- Row count and column-level documentation are absent; field semantics must be inferred after download.
- The 13.3 MB size indicates a small dataset, which may limit the scope of quantitative analysis.
- The dataset consists of image and video files, which may not contain the raw numerical simulation data for direct computational analysis.
