BB2k posted the above line and I would like to expand on it.
In some experimental data I ran across there was indeed a difference in the results of jet impingement on a flat plate by changing the shape of the nozzles (circular being among the worst). Another variable to the equation. Anyone feel like googling?

Because it changes the size of the stagnation point with a circular shape being the smallest. Also a flat plate isn't as good as a concaved plate. Another one to add to the equation. The wall flow and film is the hint.
EDIT: The shape also effects the spreading rate and turbulance levels.
