Midterm Information for Ph136B, Winter Term 2014/15
The midterm will consist of a ~20 minute presentation on a special topic relevant to the general material covered in the first half of term. The midterm grade will enter your final grade at a 15% level.
The presentation must be given on the black board, but computer projection is allowed for graphics or figures.
If you work alone on a simpler topic, your presentation should be 10-15 minutes. If you work in a team of two on a more complex topic, each team member should present for about 10 minutes (it will be up to you to divide the material accordingly). Both members of a team will get the same midterm grade.
The presentations will we in class in the lecture on Wednesday, February 4, in a special class meeting between February 4 and February 9 (TBD), and, if need be, also in the lecture on on Monday, February 9.
Below is a list of topics from which you may choose. We will have a raffle in class on Wednesday, January 28 on the order in which individuals/teams get to pick their topic. Each individual/team should look into a number of possible choices. I will also accept topics that you propose yourself, but (1) you must pass them by me before class on Wednesday, January 28 and (2) they must be understandable on the basis of the material already covered in class up until the midterm.

Here is the list of topics. Note that some of them could fill multiple full lectures -- it will be your task to distill them to their most important aspects and deliver them in a way that is comprehensible to the entire class within the alloted time.
- Equation of state of water in its three phases (1 person).
- Properties & EOS of liquid and metallic hydrogen (in Jupiter) (1 person).
- Angular momentum transport in an astrophysical accretion disk (1 person).
- Measuring air speed in supersonic flow (1 person).
- Joule-Kelvin Effect (1 person).
- Attenuation of sound waves by bulk viscosity; Stokes's law of sound attenuation (2 people).
- Derive the entropy generation equation for viscous flow given in KR 13.7.4 (2 people).
- Equations of fluid Dynamics in a Rotating Reference Frame, Ekman & Rossby numbers + a simple example, KR 14.5.1 (2 people).
- Geostrophic flows and Taylor-Proudman Theorem with application to atmospheric winds. KR 14.5.2-14.5.3 (2 people).
- Ekman boundary layers. KR 14.5.4 (2 people).
- Kelvin Helmholtz Instability. KR 14.6.1 (2 people).
- Rayleigh-Taylor Instability. Not explicitly in KR, but there is lots of literature on this instability (2 people).
- Boundary layer separation from a cylinder.
