3.10. BOUNDARY-LAYER FLOW AND TURBULENCE
3.10A. Boundary-Layer Flow
In Sections 3.8 and 3.9, the Navier-Stokes equations were used to find relations that described laminar flow between flat plates and inside circular tubes, flow of ideal fluids, and creeping flow. In this section the flow of fluids around objects will be considered in more detail, with particular attention being given to the region close to the solid surface, called the boundary layer.
In the boundary-layer region near the solid, the fluid motion is greatly affected by this solid surface. In the bulk of the fluid away from the boundary layer, the flow can often be adequately described by the theory of ideal fluids with zero viscosity. However, in the thin boundary layer, viscosity ...
