liftDir and dragDir for multi elemet airfoils
i am simulating the turbulent flow on multi element airfoils "30P-30N" that have 22inch=0.5588 stowed chord using OpenFoam.
my question is about setting the parameters of forceCoeffs function in ControlDict.
1- i should write "stowed chord" for three of them as "lRef" or not? if no, what i should write for "lref" for each of them?
2- as we know, the slat and flap of tree element airfoil, has 30 degree deflection angle. now my Question is that, what should i write for "liftDir" and "dragDir" for each of them separately?
i put my forceCoeffs in attachment, please please help me.
thank you very much:)
Have you figured out the answer for your question, I am having exactly same doubts,
What was your boundary conditions for K and W or what ever model you used. can you please share the '0' file and 'system' of the 30P30N case if you still have it.
Thanks again for your Help,
