Turbulent boundary layers [Fluid Mechanics #14]

In this video we continue our exploration of External Flows with the Turbulent Boundary Layer. Fluid moving near a wall slows down in a velocity deficit region known as the boundary layer due to viscosity. At high enough Reynolds numbers, this flow becomes turbulent and, although there is still a boundary layer, it is much different in behavior and structure.

We will explore the physical characteristics of the turbulent boundary layer, comparing to the laminar case, and meaningful flow features. Then, we will explore the shape, size, and growth of the turbulent boundary layer, leading to wall shear and drag. Because we cannot explore the flow theoretically, we resort to empirical modelling.

fantastic video please continue to make these

The turbulent tuna was an awakening moment for me 😂

Sir, can you pl explain specifically exactly how the velocity difference can create vortices or circular motion through the angular momentum ???
