3 cards from this lesson. Good the night before a test.
Try these first
- 1.
What occurs when the boundary layer separates?
Hint
Think about the effects of friction.
- 2.
Define a favorable pressure gradient.
Hint
What helps flow attachment?
- 3.
What happens at the separation point?
- Flow detaches from the surface
- Flow accelerates
- Pressure decreases
Hint
Think about where fluid flow is effectively lost.
- 4.
True or False: A favorable pressure gradient can cause boundary layer separation.
- True
- False
Hint
Consider how pressures interact with the flow.
- 5.
Derive the conditions under which boundary layer separation occurs based on a given velocity profile.
Hint
Look for points where velocity gradient changes direction.
- 6.
Design a simplified aerodynamic surface and predict its behavior with respect to boundary layer control.
Hint
Consider shapes tested in wind tunnels.
