Which Foam for vortex shedding problem
Hi all,
if I were interested in modeling vortex shedding behind a cylinder in incompressible flow, which Foam is best to use? The Re will vary from 60 to 10,000. Thanks, Maddy. 
You can start with icoFoam, the basic solver for incompressible flow. A more important question is the turbulence model you will use. There are numerous models, you can find more info on http://www.cfdonline.com/Wiki/Turbulence_modeling, but I suggest you also find a good textbook.

icoFoam for lower Reynolds number, pisoFoam or pimpleFoam for higher Reynolds number. However, have in mind that in this Reynolds number range (up to 10000) the flow exhibits a mixed laminarturbulent behavior which is quite difficult to capture properly with standard RANS turbulence models. I have some experience at higher Reynolds numbers (from 1E05 to 3.6E06) and for such a flow regime some unsteady RANS models do a pretty good job in predicting vortex shedding frequencies and timeaveraged drag values.

hi all,
Use icoFoam for Re ranging from 0300 and turbFoam or pimpleFoam for Re ranging from 30020000 with SA Model or kepsilon. Regards NAVEEN 
hi all
I am interested in vortex shedding at high Reynolds numbers (20.000 to 90.000). I found out that the solver turbfoam is no longer available in OF versions 1.6 and newer (I work with OF 1.7.x).

Both icoFoam and pimpleFoam can do simulations, and you can chose from a whole range of turbulence models in constant/turbulenceProperties.

hi all,
since icoFoam is a solver for laminar flows I did simulations with pimpleFoam and pisoFoam, which produced similar results. For any further suggestions see http://www.cfdonline.com/Forums/mai...frequency.html maybe we can continue the vortex shedding topic there. Uli
