A lot of people struggle to get decent experimental data to validate their CFD...:(

Feel free to add links other sites or repositories if you know of them :)

Many thanks!!

Very useful information there, but need password to get the detailed data.

Just click on the register big button (top left corner) and they will send you the username and password to access the data. It's free.
