Classic Collection Database

Welcome to the ERCOFTAC “Classic Collection” Database. From these pages you can access the test cases of the original ERCOFTAC Database, which was started in 1995. In 1999 the CFD group at UMIST took over responsibility for it, and following the merger of UMIST and the Victoria University of Manchester it is now administered by the CFD and Turbulence Mechanics research group in the School of Engineering at The University of Manchester.

The database has undergone some re-structuring and expansion to include, amongst other things, more details of the test cases, computational results for a few cases, and conclusions drawn from some of the ERCOFTAC Workshops on Refined Turbulence Modelling, and other such meetings. At the moment, each case should contain at least a brief description, some data to download, and references to published work. Some cases contain significantly more information than this.

The database is open to all fluid dynamicists worldwide. Obviously if you use the data from any case in publications you should reference the original authors' work.

If you have any comments or suggestions for further improvements, please e-mail or If you have experimental, or DNS/LES, data of a similar nature that you would like to make available to other researchers through this database, feel free to e-mail us also.

The links on the sidebar provide a number of methods for accessing and searching the database.

If the default theme colours do not show up well on your device, you can choose another one from the menu in the top right hand corner of the title bar (on some browsers you may have to refresh the cache before that takes effect).
