@r5a773 to set up a Velocity is not the best way to define the problem. You will define a Reynolds Number, in this case Re=100 = rho*U*D/mu -> U = Re*mu/rho/D. I`ve used water with a D=1m, U~1e-4m/s @ inlet ( green values contour plot field). In other words, we can chose a fluid( water , air, etc), a geometric scale of diameter D, and chose a Reynolds number an the velocity will be find. An exception is your code works in non-dimentional form. At Re=100 we can see the von Karman vortex street, and the 2D approximation is good. Thanks for interest!

На какой скорости происходят эти завихрения?
