Errorneous velocity near walls while using wedge type BC for axisymmetric flow

I am solving axisymmetric flow problem of flow between two rotating cylinders using rhoCentralFoam using wedge type BC. I generated the mesh in GMSH and converted it into openFoam using gmshToFoam utility.
But when I am running the simulation, I am getting non-zero radial velocity near the outer rotating cylinder, which ideally should be zero.
The Uy and the velocity vector plots near the outer rotating wall
The rotation is about X axis. Hence Uy is the radial velocity component.
Can some one tell why is this happening ?
