was not trying to second guess you - more worried about the simulation itself.
even if the Reynolds numbers different it would just mean we are simulating the wrong speed a bit. If the simulation math is wrong we could be simulating flow on Saturn or worse - flow in a cartoon world that is completely unattached to reality.
I guess I was expecting somebody with a kamm back to get flow like below.
even the snow cone looks like the flow is trying to separate down the back.
I just thought of something
Could just drop this pic in the simulator and try it and see how it compares
That is about as close to a head to head against reality as we may be able to get
not sure i will get it done tonight though
