7.38, §2 P.D.E. Model

Finite domain :
Unknown velocity potential
Elliptic equation
One Neumann boundary condition at r=1.

Try separation of variables:

Boundary conditions in the -direction are periodic: u must repeat itself after every increment in .Periodic boundary conditions classify as homogeneous (u=0 satisfies them.)
