Fluid mechanics

What does a tsunami have in common with usual surface waves? How does an airplane wing work? And why does the wind usually work against you when riding a bike (even when the wind is from the side)?

Information for admitted students Spring 2021

Congratulations! You have been admitted at Stockholm University and we hope that you will enjoy your studies with us.

In order to ensure that your studies begin as smoothly as possible we have compiled a short checklist for the beginning of the semester.

Follow the instructions on wether you have to reply to your offer or not.


Checklist for admitted students

  1. Activate your university account

    The first step in being able to register and gain access to all the university's IT services.

  2. Register at your department

    Registration can be done in different ways. Read the instructions from your department below.

  3. Read all the information on this page

    Here you will find what you need to know before your course or programme starts.


Your seat may be withdrawn if you do not register according to the instructions provided by your department.

Information from the department - courses

Welcome to your studies at the Department of Meteorology, Stockholm University.

All accepted students receive a welcome letter via email with important information for their studies.

Roll Call

At MISU, the course starts with a mandatory roll call. You will get more detailed information about the roll call via email. If you plan to start the education but for some reason cannot participate at the roll call, please contact our study counselor. Otherwise you risk losing your spot in the course. Contact information for the study counselor is listed at the bottom of this page.


If you are accepted to a course, you can register for it through your University account. If you have problems registering, please contact our study counselor. Contact information is listed at the bottom of this page.

Conditionally accepted

If you have been accepted with conditions then you must contact the study counselor before you can start the education. Please do this as soon as possible and well ahead of the start of the course. Contact information is listed at the bottom of this page.

On a waiting list

Have you received information that you are on a waiting list for a course? You will always be contacted by us via email if you are accepted. Generally, we do not accept anyone from the waiting list beyond 1 week into the semester.

Find your way to MISU

MISU has its own lecture rooms and all of them are in the same corridor as the rest of the department. You will get your own entry card for access to the department. MISU is located on 6th floor, building C in the Arrhenius Laboratories.

Classes during the spring semester 2021

Classes will be done in hybrid mode at MISU. That means that lectures can be attended onsite by a maximum of 8 participants, but that the lectures also are broadcast online. Some parts of the course may require physical presence. You will be informed if that is the case during the course and attending will be according to current regulations. We are trying to set the schedule so that rush hour commuting can be avoided as much as possible. Most staff members are working from home to facilitate for classes. Read more about how we have adjusted MISU for teaching during the Corona pandemic.

You can get more detailed information about each course via the teaching platform Athena. You will get access to each respective course page as soon as you activate your University account and have been registered for the course. If you have any questions, please contact the study counselor (contact information below).

Welcome activities

Stockholm University organises a series of welcome activities that stretch over a few weeks at the beginning of each semester. The programme is voluntary (attendance is optional) and includes Arrival Service at the airport and an Orientation Day, see more details about these events below.
Your department may also organise activities for welcoming international students. More information will be provided by your specific department. 

Find your way on campus

Stockholm University's main campus is in the Frescati area, north of the city centre. While most of our departments and offices are located here, there are also campus areas in other parts of the city.

Pre-departure information

New in Sweden

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. The subject 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.

The basic concepts and equations of classical fluid mechanics are introduced, and the difference between flows with very large and very small viscosity is considered.  Exact solutions for a few very simple flows are presented, as well as approximate methods for other flows. The second part of the course deals with geophysical fluid dynamics. The fluid mechanical concepts and equations are here applied to large scale flows in the atmosphere and the ocean.


  • Course structure

    Lectures and problem solving sessions in the course will be given in "hybride format" where you can either follow them on campus or remotely through zoom. It begins with an introduction to vector analysis, the mathematical language of fluid mechanics. Then the Navier-Stokes equations are derived, and basic concepts introduced: vorticity, viscosity and Reynold's number. Some steady solutions are studied, and simplified equations for boundary layers and creeping flows. The second part of the course begins by examining flows in rotating systems. Then the properties of the rotating shallow-water equations are explored: conservation of potential vorticity, geostrophic adjustment, Poincaré waves, Rossby waves, and instabilities.

    Teaching format

    The teaching consists of lectures, tutorials and laborations.

    Course material

    Grading criteria, course literature and other material and correspondence related to the course will be available on the course Athena-site at once you have registered for the course.

  • Schedule

    The schedule will be available no later than one month before the start of the course. We do not recommend print-outs as changes can occur. At the start of the course, your department will advise where you can find your schedule during the course.

    You can search for schedules from previous years in TimeEdit, by entering the course code.
