Don't forget the exam is in class next Tuesday!
Class notes
Scanned Notes
The main points of the lecture were
Goals:
After this class you should be able to:
- Use dimensional analysis to determine the number of dimensionless groups involved in a problem.
Reading
- The class notes.
- WWWR, chapter 11; BS&L, chapter 3
- Multi-Media Fluid Mechanics: Work through Kinematics: Streaklines.
Use of colored dye markers can produce some very beautiful patterns!
Additional Readings:
In class we talked about the example of estimating the yield of a point explosion
through dimensional analysis, solved for early atom bomb tests by G.I. Taylor. A nice
discussion of his result is provided
here,
and a somewhat grainy reproduction of the actual images used in Taylor's study is
given here. It's a good
illustration of the power of dimensional analysis to solve complicated problems.
Demonstration:
Stokes Flow Reversibility
