manu551 New Member Join Date: Nov 2016 Posts: 13 Rep Power: 9	Hi you all, I tried modelling a circular cylinder with k-w SST model in pisoFoam, but results aren't so good... Cd is quite ok, instead St number is about three times is real value (0,2). Have you got any idea? Inlet flow has Re=30470 and I=2%. Thanks.
