Fluid mechanics describes and explains many natural phenomena that we can see around us every day. It also has a lot of applications in industry, physics and other sciences, from astrophysics and climate science to medicine. It is one of the oldest branches of physics, and suitable for learning various mathematical methods in an intuitive way. But it also has its own distinct style, different from much other physics. This is a consequence of the central role of nonlinearities in fluid mechanics, which for example gives rise to turbulence. As a result, most problems even in basic fluid mechanics do not have an exact mathematical solution, but by using various approximate methods it is still possible to extract valuable information from the governing equations.


The course will run during the entire fall semester, with evening lectures. It contains both classical fluid mechanics and geophysical fluid dynamics (which describes the flow in the ocean and atmosphere).

The course is given for student following the research branch of the bachelor program in physics. It is also a course that students following any of the bachelor programs in meteorology, physics or astronomy can chose as an optional course. It can also be a course interesting for the master students.

The course will be open for late registration on July 15.

Lecturers: Jonas Nycander (MISU, jonas@misu.su.se) and Dhrubaditya Mitra (Nordita, dhruba.mitra@gmail.com).

Text book for part of the course is "Essentials of Atmospheric and Oceanic Fluid Dynamics", Geoffrey Vallis. The rest will be covered by written lecture notes.
