viscous sublayer [‚vis·kəs ′səb‚lā·ər]

(fluid mechanics)

In a turbulent flow, a very thin region next to a wall, typically only 1% of the boundary layer thickness, where turbulent mixing is impeded and transport occurs partly or, if the limit as the wall is approached, entirely by viscous diffusion.
