the classical problem of the flow around a Cylinder Re=35?
 

Dear friends
I have modeled the classic problem of the flow around a cylinder. The textbook says that I should get two laminar vortexes after the cylinder when 15<Re<40 but my results are very similar to the potential flow solution. I employed the laminar viscosity model. Any tips?
Thanks

Check domain dimentions.

Hi
I Agree with Figd84. We must choose the dimension before. In GAMBIT, the default of size is in meter.

Thanks for your responses guys. I actually considered the fact that the mesh is created in meters in Gambit. The good thing is that the default for Fluent is meters.
Any idea?

15<Re<40 is very small reynold number. It's just like fish moving in water!!! please read this: http://jilawww.colorado.edu/perkinsg...lds_number.pdf
Hope it helps
