In this video, we pivot from enclosed flows (pipes/channels) to external flows like boundary layers. A boundary layer is a thin region of flow near the wall that is slowed down due to viscosity and the noslip condition at the wall. It is critical in our understanding and prediction of many real world flows.

We will try and solve the boundary layer theoretically, arriving at the famous solution that Prandtl and Blasius did many years ago. We will explore how the boundary layer grows in the streamwise direction, what shape it has, and how it generates stress and force on a surface. All equations in the lecture are specific to laminar boundary layers.
