CL_max in CFX

    • Sapir.Argavani


      I'm trying to run an airplane at large angle of attack 

      I have a problem with my results, the wings are stalling at smaller CL and angle of attack then reality. 

      When I checked the imbalance I noticed that the rethetat is not equal to zero. I have checked the mesh already and now I am checking the size of my domain. 

      I would like to know if there is any method  of the solver (or other tips in general) which can help me solve this problem or if its.

      Thank you

      Have you checked the flow field? Is there unexpected boundary layer separation happening?

      Also, did you try to perform a mesh refinement study , specially near the boundary layer of the airfoil?
