Details about our online courses

The courses Kontrolle turbulenter Strömungen [27] and Methoden der Datenanalyse in der Thermofluiddynamik [28] will be offered completely online via ISIS (KTS [29], MDTF [30]). The contents of the lectures will be provided by screencasts. In addition, there will be online meetings once a week as well as a forum available for questions and discussions about the teached contents. The first appointment will take place live in virtual presence. For

KTS: on Tuesday, 21/04/2020 at 2.15 pm (see ISIS [31]),

MDTF: on Friday, den 24/04/2020 at 10.15 am (see ISIS [32]).
