Boundary layer flow over a wing surface begins as a smooth laminar flow.
There are two different types of boundary layer flow : laminar and turbulent ."
If the buoyancy dominates over shear production, the boundary layer flow is in free convection.
A boundary layer flow was created on both sides of a thin rigid flat plate which terminated with a square trailing edge.
The buoyancy generated turbulence peaks in the afternoon, hence the boundary layer flow is in free convection during most of the afternoon.
From this solution, it is possible to characterize the convective heat / mass transfer constants based on the region of boundary layer flow.
A sharp interior angle in this region can interact with the boundary layer flow causing a drag inducing vortex, negating some of the benefit of the winglet.
The full model was tested in different stages of construction in turbulent boundary layer flow, complete with the local topography to model the wind conditions at the site.
The system uses a fan inside the tailboom to build a high volume of low-pressure air, which exits through two slots and creates a boundary layer flow of air along the tailboom utilizing the Coand effect.
Using scaling arguments, Ludwig Prandtl has argued that about half of the terms in the Navier-Stokes equations are negligible in boundary layer flows ( except in a small region near the leading edge of the plate ).
