Which Turbulent Model is Suitable at Re=3900?
 

Dear

I am trying to simulate the flow over a cylinder at Re=3900. I used k-epsilon model and k-omega model, but I didn't get any vortex shedding and my lift coefficient didn't oscillate. Could you please help me, which turbulence model is suitable for this flow? Or any other direction?

K-Omega plus SST?

Thanks! Jesse,

But some time before I have used k-epsilon realisible model and got excellent result both Cd and vortex shedding. Could you please tell me which turbulent model is useful at Re=140000?
