Like in an infinite flow, we find that laminar boundary layer, transition region and turbulent boundary layer also exist along a flat plate in open channel flow boundary layers.
The analysis result of velocity distribution and boundary layer thickness is put forward in the boundary layer and cored region for laminar and turbulent flow of pipeline.
