The two-dimensional benchmark test, also called the “IEA 2D test case”, was defined in 1990 to be used in the IEA Annex 20 work, but a significant number of papers have used this geometry in other CFD work.

We believe that it is attractive to a new user to stick to a geometry used by a number of other researchers. It is possible to compare the results with other authors’ results (other turbulence models, other numerical schemes, etc.). The basic knowledge behind the benchmark test has thus expanded during the years and made the test case more useful.
