ivanddd is on a distinguished road

I started to solve axi - symmetric flow in OpenFOAM. There was problem with continuity. Where is larger area, there should be smaller speed but the problem can be seen from figures. At the end of the domain is higher speed than at the start of the domain. At the inlet is smaller area than at the outlet.
The boundary conditions were :

inlet U, p...zerrogradient
outlet p...0, U zerrogradient
wall ...
wedge boundary condition at the side of the domain

I don't know if I used correctly the wedge boundary condition.

Thank you very much for your answer, Ivan.
