Default Flow around a cubic obstacle - LES or DNS

Posts: n/a

I am preparing a presentation about flow around obstacles, and I do need a picture of a instaneous velocity field around a cubic obstacle (instataneous, not time averaged). It is to illustrate the differences between the intantaneous fluid flow pattern and the time averaged.

Does anyone have this picture or knows a reference, or home page, where I can find it ?



PS.: Obviously, the source of the picture will be clearly displayed with the picture during the presentation.

In the Gallery Section of there is a gif animation of impulsively started flow around a cubic bluff body (in its plane of symmetry, and at the initial stages of the wake development).

If you want "pictures" of the wake at later stages, so that you can clearly see the unsteadiness of the wake then check reference 6 in the publications section of the same web site - it's an AIAA conference paper.
