Shear layer data compilation

Flow data from shear layer experiments and simulations presented in an open, modern, and unified format.

NOTE: This project is going through a redesign from the ground up. I am investigating moving the extract-transform-load stages to C or Fortran, with goals of making the project faster and more portable (less dependent on the Python ecosystem and the quirks of the SQLite version of a given Python distribution). I am also investigating moving more analysis code from Python to SQL.

Goals

• Single SQLite database as primary output file.

• Python module to load and use SQLite database.

• Documentation also serves as a data and literature review for different flow classes (for use in meta-analyses and other work).

• CSV files as input files. SQLite database file and PDF documentation file as output files (released under CC-BY-4.0 license).

• Uncertainty quantification and data validation for as many cases as possible.

• Emphasis on archival quality and long-term access.

  • Library of Congress recommended formats statement

Previous tabulated data compilations

I have already conducted a literature search to identify relevant individual studies to include in the database. However, many previous data compilations already exist and provide an extensive amount of data in an already processed format that is ready for both reference and study. All of these compilations are older and presented in tabulated form, which requires digitization for use. I identify several of these previous data compilations below.

Note that some of these data compilations provided data in a digital form distributed with the reports, not as printed tables.
