Class notes
Scanned Notes
The main points of the lecture were
- The Streamfunction: Flow Past a Sphere
Goals:
After this class you should be able to:
- Solve axisymmetric problems using the axisymmetric streamfunction.
Reading
- The class notes.
- BS&L, chapter 4
- Multi-Media Fluid Mechanics: Work through Kinematics: 2-D Flows and Vorticity.
Additional Readings:
Fluid mechanics is important in a wide range of biological systems. At the cellular
level the Reynolds number is usually quite low, and viscous forces are dominant. At
the organism level the Reynolds number is usually high and inertial forces are
important. Occasionally flows are so fast that cavitation
effects are important! A really cute example of such a flow is the phenomenon of the
snapping shrimp, described
here. Be sure to look at the link
near the bottom of the page to the detailed physics of the problem!
