What is the surface boundary condition for a thin airfoil at a subsonic flow? (Where shape of the airfoil is represented as y = f(x))

Question

TuteeHUB · Accepted Answer

(  frac {  }{ y} =   frac {df}{dy}  )

TuteeHUB · Answer

(  frac {  }{ x}  ) = V    (  frac {df}{dx}  )

TuteeHUB · Answer

(  frac {  }{ y} =   frac {df}{dy}  )

TuteeHUB · Answer

(  frac {  }{ x}  ) =   V  (_ ^2   frac {df}{dx}  )

TuteeHUB · Answer

(  frac {  }{ x} =   frac {dV_ }{dx}  )
