thanks for the pointers! I'm way out of my element here and just thrown together something with the first software I found on internet. about this: > the leading edge of the foil should be rounded off I agree, however, in the first round of simulations the leading and trailing edge where they themselves giving a lot of lift to the foil (especially the trailing tapering), so in my naivety I slabbed both edges to reduce those effects and see if the flow was deflected by the slab alone. interestingly, even if the model itself is flawed and the simulation technicalities off for the intended purposes, having the slab slightly forward gave also interesting results, almost the same lift and a lot less drag 1) https://i.imgur.com/TudMHlX.png https://i.imgur.com/TudMHlX.png 2) https://i.imgur.com/GjiVL8s.png https://i.imgur.com/GjiVL8s.png so I came up with an idea for a foil that's still easy to craft out of foam or balsa and does use the different effects do redirect the flow more effectively 3) https://i.imgur.com/n9RUHs5.png https://i.imgur.com/n9RUHs5.png of course all of this is purely based of a low resolution simulation, still, it was fun. I've no chance to test them in practice tho.
