From the looks of it, you can see that the "wake" pattern seems to be the same. Pretty sure that it can be even closer with some further tweaking of the velocity and viscosity.

So, it is possible to simulate with a certain precision, but as stated previously, it requires you to know what the flow should look like. Quite an interesting result nonetheless !
From the separation and wake depiction this must be sub-critical Reynolds number flow,with laminar boundary layer.
And that's too bad because we need turbulent boundary layer flow to help on our projects.
All the separation points are going to be premature.Drat!!!!!!!!!
