Modeling fluid flows in geophysics, ACM Seminar

MAP6939-0010, Fall 2014

Monday 4:10-5:10 PM, LOV 104

The emphasis of this seminar will be on reduced flow models (potential flow, complex-variable methods, etc.), porous-media flows, and land-formation processes such as erosion and dissolution. We might also discuss thermal convection and ocean/atmosphere flows. A course in fluid dynamics will be helpful but not necessary.

Throughout the seminar, we will be reading various research papers related to geophysical flows. I will occasionally ask students to summarize a paper and lead a class discussion on it. Additionally, I will arrange for guest speakers to present talks on related topics. If you are interested in giving a talk, please contact me. All are welcome.
