Hi everyone I want to simulate flow around cylinder and want to capture Karman vortex streets. Is it possible using Fluent-6. If possible What should be time step size and how many time steps. How fine grid should be and what is appropriate turbulence model.

Hi

Search for unsteady validation on fluent wed side under the title

"unstedy laminar flow behind a circular cylinder"

In addition there is a lot of CFD done by Rody, yes, the famous german Wolfrang Rody, who has contributed to develop most of the turbulence models.

Moreover, I suggest that you read the work of Koobus Bruno, Farhat Charbel, Tran Hai "Computation of unsteady viscous flows around moving bodies using the k-e model on unstructured dynamic grids"

Have fun! BTW, where are you in the middle east? Alex Munoz

Hi Alex Munoz Thank you. I have searched the references you mentioned and found very useful informations.
