Class notes
Read through pages 283-294 of the notes and view the online narration below. Don't forget to complete the quiz in Canvas!
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.
- BS&L, chapter 4
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. A Physics Today article on the history of Prandtl's boundary layer theory and
experiments is 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.
