Boundary layer is actualy a thin layer of fluid that slows down on the surface of the solid that the fluid is flowing on.

The slowing down of this fluid is due to the adhering of the fluid molecules nearest to the surface of the solid due to the intermolucular forces.

This boundary layer can be reduced by introducing turbulance..
And the impingement is the best kind of turbulance to break the boundary layer. It simply breaks it and "new water" (fresher) comes in contact with copper.
