I’m looking for knowledge about the multi-element wing design process and method.
I currently need to design high lift 3 sections airfoil (including fixed slat, main wing and slotted flap) for Re=0.3 million. CFD is the tool I have. The factor I care most is the lift coefficient. As the Re is low and few published 3 sections airfoil design for this low Re can be found online, I guess the design work will be as listed below.

- I need to parameterize the geometry shape of each of the three sections then optimize these parameters to optimize the geometry shape of all the three sections. Unfortunately, after searching for a long time, I haven’t found any documents on this.
- I need to optimize the relative position and deflection angle of each the three sections. Thanks to the work of NACA and other institutes. I found a lot of papers on this. I surprisingly found that since the number of variables is large, people use complex data mining method to optimize these positions variables.
