Hey all,

I was looking online for a nicely described cylinder with vortex shedding validation testcase (high reynolds) but I was not able to find anything. I would like it to have computational domain description, boundary conditions and results. Any suggestions?
Thank you!

How high Reynolds number?

Hi Lefteris,

Thank you for your reply.
You are right. High is relative. I would like to try several cases. From 90 to 10^5 or even 10^6 and check how the vortex shedding in affected.

Hello giodan!

Well, I don't think that at such Reynolds number you'll have any vortex shedding rather than a fully turbulent wake (after the critical Reynolds). Anyway, I think that a good source for papers is nasa's website. You may find something useful over there.

Actually you can have vortex shedding at Re > 10^6. A good reference with experimental data (if you can get it) is

G. W. Jones, Jr., "Unsteady Lift Forces Generated by Vortex Shedding about a Large, Stationary, and Oscillating Cylinder at High Reynolds Numbers", ASME Symp. Unsteady Flow, 1968.

The same author has published several works in a similar vein under the auspices of NASA. Look for NASA Technical Report R-300 by Jones, Cincotta, and Walker.

Another reference is Roshko, "Experiments on the Flow Past a Circular Cylinder at Very High Reynolds Number", Journal of Fluid Mechanics 10, pp.345-356.

Actually, he/she is not interested in Re>10^6 rather that is his/her upper limit so in answer to giodan's question those papers are quite irrelevant for that case.

Thanks for the references though

Thank you!
Giodan, I did this topic for my Master's thesis. Perhaps my thesis will be a good starting point for you. At the very least the references will give you some papers to read.
