Aerodynamics - Laminar and Turbulent Seperation
3 important questions on Aerodynamics - Laminar and Turbulent Seperation
Why is flow seperation important?
- Loss of lift (airfoil)
- Increase of pressure drag
- Generation of unsteady loads. (could hit stabilizer)
How will the graph look when there is friction?
Flow seperated before thickest point
Difference is Delta Cp = 2
==> suction in the back
Turbulent flow (high reynolds number):
Sticks to surface longer
A lot of pressure drag!
Why does turbulent flow sticks to the surface better?
The question on the page originate from the summary of the following study material:
- A unique study and practice tool
- Never study anything twice again
- Get the grades you hope for
- 100% sure, 100% understanding
