Vector field

A one-semester course for students in the Chemical and Energy Engineering Master’s program at the University Otto von Guericke of Magdeburg

Dear students:
This course is now retired, and this page will no longer be used. Professor Andrea Beck is taking over the fluid dynamics course in 2021 — I am super excited! Please head over to her Moodle course to register. It’s been a huge pleasure working on this for the last five years! I will now focus on completing my PhD. Take care!
Olivier.
