I'm trying to help my daughter prep for CFI check ride. So she asked why does it increase lift at thicker ratios? My first thought was just due to increased distance on the top, assuming not symmetrical, thus creating more differential of pressure? But then I went down a rabbit hole of Reynolds numbers and delayed separation lost myself and confused her.

I did a search and found this graph and several like it in my Dan Raymer textbook, but even the graphs with specific airfoils did not explain the why they just showed the result.
Thanks for any insights.
