Flow past a 2D-Cylinder ?
 
Hi,

I would like to simulate a flow around 2D-Cylinder using CFX 4.2. I really want to see the vortex street downstream of the cylinder. Could anyone share your experience in doing this ?

Thanks

Hi Dwi,

2D-cylinder flow is fairly easy to model with CFX. I have got a simple model of Re=100 flow with a vortex street on my home page:

Make sure you have good grid quality and grid resolution in the cylinder boundary layer. I can send you the command file and/or geometry file if you like.

You should be able to find lots of references if you do a journal or web search.

Regards Glenn

Hi,

Take a look at the projects on the www-site http://www.bunova.nl They used the Low Reynolds Number k-w model (Wilcox, 1994) for simulating the flow around a cylinder using CFX4.2. Although the text is in Dutch, it might be a useful link.

Cheers, Gert-Jan
