Laminar and Turbulent Boundary Layers

Laminar and Turbulent Boundary Layers. A boundary layer may be laminar or turbulent. A laminar boundary layer is one where the flow takes place in layers, i.e., each layer slides past the adjacent layers. This is in contrast to Turbulent Boundary Layers shown in

As the lamina r boundary layer increases in thickness, it becomes unstable and nally transforms into a turbulent boundary layer in which the uid particles move in haphazard paths.
