Yeah the lift equation you wrote is the one I mentioned in my post. I just put p for rho as that is the notation for freestream density the book I have uses; it has a rotated by a right angle 8 as well, showing it is freestream density.
I understand all you said except how have you pointed out that in fig. 1 (i.e. the graph) the separation ocurs at 30% of the way back from the LE? I would this that it is at 0.2 (i.e. 20%) because that is where the pressure rises. Can you reply on this please? thanks.
Lafayette.
thanks for responding to my questions!!!
I was looking at the first plot, and the spike that occurs at 0.2 looks a little
suspicious to me. It occurs before the thickest point on the wing, which
doesn't seem right, and it is very abrupt. I am viewing that as a likely
spurious value. If JavaFoil gives you the option to run a more precise analysis,
I would be tempted to do that.
Boundary layer separation, if it occurs, will tend to occur a short distance
after the negative pressure peak.
