Computation of incompressible potential flow using von Mises coordinates

Incompressible potential flow over symmetric airfoils has been formulated in terms of von Mises coordinates. This formulation provides a rectangular computational domain with Dirichlet boundary conditions for the single unknown y(x, ψ). The governing second order nonlinear pde is solved by SLOR on uniform and clustered grids. The method proves to be accurate, efficient and easy to code.
