CBE 30355 - Lecture Notes - Oct. 30, 2018
Announcements
The second hour exam will be one week from today! Because of the AIChE meeting I will be in Pittsburgh - so class today will be online. I'll record a video of the lecture which will be linked below, and you can look at it at your convenience!

Scanned Notes
The on-line video lecture.
The quiz is available in Sakai, and needs to be completed after viewing the videos and before the class next Thursday.
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
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. A Science
article describing the details of the phenomenon is given
here.
