Velocity and Thermal Boundary Layers — Lesson 2

This video lesson discusses two types of boundary layers. The velocity boundary layer is generated due to a sharp fluid velocity gradient that exists because of no-slip conditions at the solid surface. A thermal boundary layer is generated where a temperature gradient is observed. For a flat plate of infinite length, a thermal boundary layer is formed near the wall, and the fluid temperature varies between the wall temperature and the freestream temperature at the edge of the boundary layer.
