What is a controlling factor of turbulence and skin friction?
- Aspect ratio.
- Fineness ratio.
- Countersunk rivets used on skin exterior.
Explanation
Fineness ratio describes the streamlining of a body or aerofoil, comparing its length to its maximum thickness. A well-chosen fineness ratio keeps the airflow attached and laminar over more of the surface, controlling where transition to turbulence occurs and how much skin-friction drag is generated. Aspect ratio relates instead to induced drag.
