Try this software:

Not exactly what you want, but very interesting to learn from, indeed.
It would be good for you to study about Airfoil Pressure Distributions at:

Besides, find an interactive java diagram at:
http://www.desktopaero.com/appliedae...etryandcp.html
Diagram #2 is closer to reality, I believe, since the little bump of #1 cannot deflect air as shown.
Such a bump can induce some turbulent flow only, which could help the lift only if used on the upper surface (it is called turbulator).
