Validation Cases
Test cases and databases that can be used for model development, benchmarking
or verification of codes. For a good introduction to code validation and verification
see the
NPARC Alliance, Tutorial on CFD Verification and Validation.
- ERCOFTAC NEXUS Portal to Fluid
Dynamics Database Resources
![[GOOD]](Icons/smiley.gif)
- A portal to several databases compiled by Ercoftac members. The site includes
the classical Ercoftac database from 1995, a distributed experimental database,
a DNS database and a flow visualization database. You can also find links
to databases published by Ercoftac Special Interest Groups like the Turbulence
Modeling SIG, the Transition Modeling SIG, the Turbomachinery SIG and the
LES SIG. Most database are freely available. Highly recommended!
- NPARC Alliance CFD Code
Validation Web Site
- A large database of test cases used to validate the NPARC flow simulation
package (WIND). The main focus is on Aerospace applications. Most cases are
very well documented and some even include computational grids that you can
use directly. They also invite people to submit validations using other codes.
Highly recommended!
- FLOWNET Test Case Database
- A database with many test-cases. Some includes experimental data but most
often you will have to contact the authors to get any data. You can also
find papers presenting CFD results for some of the cases. You have to register
to access the site but it is free. This site looks very useful!
- AGARD Test Cases for the Validation
of Large-Eddy Simulations of Turbulent Flows
- A wide range of test cases focused on LES simulations. Includes a lot of
data, including correlations etc. You can download and print all documentation
yourself. The database was compiled by AGARD in 1997. Highly recommended!

usually well documented. Some parts are in Japanese. Established by the Japan
Society of Mechanical Engineers, Thermal Engineering Division.

Database
- A database with test-cases collected by the MARNET-CFD EU thematic network.

- Flapping Foil Experiment
- Oscillatory turbulent boundary layer and wake of a two-dimensional hydrofoil.
The hydrofoil is mounted in a water tunnel on the centerline and upstream
there are two small hydrofoils ("flappers") symmetrically offset from
the centerline that are driven to pitch in phase. Very well documented on
the web!
- Standard Configurations
for Unsteady Flow Through Vibrating Axial-Flow Turbomachine Cascades
- Many test cases related to aeroelasticity in turbomachinery. The database
contains 11 different two-dimensional cascade geometries and includes a lot
of information about the unsteady flow around the vibrating blades. They
claim that it is the most comprehensive database of its kind in the open
literature.
- High Speed Flow Fields (HSFF) Workshop,
University of Houston
- A number of (~14) well documented test cases for the workshop. Data is
available directly on-line.
- Surface Ship Model 5415
- A towing tank model of a modern naval combat vessel. The case is very well
documented on the web and you can download a lot of experimental data. A
very nice validation case for this type of applications!
- Third Computational
Aeroacoustics(CAA) Workshop on Benchmark Problems
- Has several well documented CAA test cases. The main focus is on fan noise.
- Convection-Diffusion
Forum Benchmark Problems
- Simple CD test cases. The specifications of the problems and a few contributed
solutions are available.

1995 ICASE/LaRC Symposium on Visualizing Time-Varying Data.
- JFE Databank
- Datasets from ASME Journal of Fluids Engineering.
- Superpipe Data
- Experimental data from the "Superpipe" at the Gas Dynamics Lab
at Princeton. The Superpipe is a large experimental rig designed to investigate
fully developed turbulent pipe flow over a large range of Reynolds numbers.
A state of the art facility!
