s.m is on a distinguished road
hi dear all,
i am analyzing the flow on multi element airfoil, using openFoam, i add the attachment file to the controlDict for obtaining the forceCoeffs on the 3 different elements (slat, main, flap).
Now my question is, when i want set "lRef" and "ARef" in it, what should i write for them?
i put the Stowed chord for each of them and i gained very bad result, what should i do to have a good results for "cd and cl" on my 3 element airfoil.
Regards.
