4 Questions
What is the difference in skin friction between turbulent and laminar boundary layer flow?
Laminar skin friction is about one-third that for turbulent flow
What is a characteristic of the turbulent boundary layer's velocity profile?
It has a fuller velocity profile and higher local velocities adjacent to the surface
What is the relationship between shearing stress and velocity gradient in the laminar boundary layer?
The lower velocity gradient of the laminar boundary layer corresponds to lower shearing stress
What is the nature of the transition to turbulent boundary layer flow?
Natural and largely inevitable
