Very small recirculation length for flow over a circular cylinder
 
Hii,

I am running the circular cylinder case for Re=3900 using various LES models (oneeqeddy,locDynOneeqeddy etc), but getting very small recirculation length. I am taking a time step of 1e-4 and running till time=2 s. can someone please let me know if he/she has got correct results for a similar case?

Thanks,
Tarak

Hi Tarak,

I have seen your two posts on the simulation of flow around a circular cylinder with LES models and currently am doing exactly the same case. My first thought on your result is that the running time is too short and 15 s should be good.

Are you doing this case in 2D or 3D? Can you give more information about the simulation?

Regards,
Albert

Hii,

Did you have any luck with this case? Were you able to get a good recirculation length? I am still not being able to get good results.

Thanks
