multiple airfoils at once, are they affected?
2 Attachment(s)
To be more practical, I tried to analyze multiple airfoils at once.
I will explain attached pictures: -There are multiple seperate rectangles. -Each of them is splitted with different airfoils. -boundary conditions are first defined, and faces(flow domains) are then seperately defined.(I defined fluid regions differently.) -mesh is fully tets, with a simple size function (made in gambit) I am looking for drag and lift coefficients. kw-sst is used. Now, the question is: Are the results get affected by others? I mean, does the flow properties of first one affect second flow domain? I tried with 4 airfoils at once(lets say airfoils a, b, c, d) then 2 airfoils at once(a and b), then other 2 airfoils at once (c and d) and the results are different for same airfoils... I can not understand why? |
