The homework assigned today has been revised slightly. Print out the
new version if you printed it out prior to this message going up!
Class notes
Scanned Notes
The main points of the lecture were
- Complex Boundary Layer Flows
Goals:
After this class you should be able to:
- Show how boundary layers grow in favorable or adverse pressure gradients.
Reading
- The class notes.
- Middleman, section 9.3.
Additional Readings:
For homework this week you are asked to solve for the velocity profile in
boundary layer flow along a flat plate with suction - one of the techniques used to
control boundary layer growth and separation. For a good short discussion of the
various approaches to boundary layer control, check out the link given
here. A really lovely picture of the
effect of suction on boundary layer separation over a wing may be found
here.
Another link at the same site (given
here)
has some interesting examples of experimental planes where the technique was used.
