  I test 2D cylinder(D=1m) in Re=100(Laminar)
  we can see Karman vortex, and i got Cd=1.3xx
  I think 1.3xx quite good.
  I retry 2D cylinder(D=2m) in Re=100
  The change is that the velocity has decreased by half.
  Then i got Cd=3.xx.
  I know Cd is depend on Re and form...
  I don't know why Cd is different..
  My English is bad.
  Thanks read my question. :)
