Imagine:
I want to compute numerically a POTENTIAL STEADY and INCOMPRESSIBLE flow over an airfoil. The set up of the problem is:
\nabla^2\phi=0
\nabla\phi \cdot \overline{n}\big)_{x=surface}=0 no normal velocity component on the airfoil surface.
\nabla \phi=\overline{U_\infty} as x\rightarrow\infty external flow at large distances.
The three main questions which arise are the next:
i) Is it possible to obtain an steady solution of this stuff?
ii) Am I going to obtain any Lift force?. Why?
Thanx for participating in this discussion.
