Hello mate here is your answer.

Boundary layer, influid mechanics, thin layer of a flowing gas or liquid in contact with a surface such as that of an airplane wing or of the inside of a pipe.A range of velocities exists across the boundary layer from maximum to zero, provided the fluid is in contact with the surface.

Hope it helps you.
