Let's Talk Calculus
JimTrainor,
I'd be a little suspicious of the pressures out of Javafoil for big surface deflected 60 deg., especially on the low pressure side. This raises an omission I made before. To get the force, you need to integrate the pressure difference between the two sides.
In normal English, streamlines are the paths that massless particles would travel in the flow. They are not lines of constant velocity.
