1 ERCOFTAC UFR 2-02: Flow past a square cylinder
1.1 Description
For a full description of the case see:
http://qnet-ercoftac.cfms.org.uk/index.php?title=Flow_past_cylinder
U_in = 0.54 m/s with 2% turbulence
Re_D = 22 000
Size of the square cylinder is 0.04 m wide and 0.392 m high.
Its situated in a tunnel with a width of 14D = 0.56 m.
1.2 Results
Experimental values are:
The Strouhal number is around 0.132
Drag coefficient is around 1.9-2.2
1.3 Notes
In the case directory there is a perl script called generateMeshDict.pl.
This script will generate the blockMeshDict file given input arguments. To see what they are just run it without any input arguments and
it will write some helpful usage info.
1.4 Download
The application to use is pisoFoam and the case can be downloaded here
