Requirements and recommendations:
Fluid mechanics
Aim of the event:
In most technical processes fluid working media moving through machines and apparatus and form the basis for the aimed energy conversions. The lecture deals with fundamentals and technical realisations of these machines. The students should learn about the operating charcteristics of different types and be able to choose appropriate machines for a given application.
Target group:
Students of process technology and plastics technology and of production and product development
