Hello,
I wanna know how to find the exact location flow separation.

Assume a wing at 15d AOA and after performing a CFD analysis, from the velocity contours I can see that there is a flow separation. Now, I need the exact distance from the LE where the flow separation starts!

1) What chart can I use to find this out and how do I use the chart? (can I find out by Cp vs X/c plot)?

2) How to plot the chart on fluent?
