Learning target / Competences
|
The students know in-depth fluid dynamics and mechanics of thermal and hydraulic turbo-machinery. They know about different types of steam generators and understand their requirements with respect to fluid mechanics and heat exchange in two-phase-flow. The students are aware of instabilities, which can occur when operating steam generators. The students are able to formulate a specification sheet for the main components of thermal power plants. Optimization strategies for the operating conditions of power plants can be judged and examined in a qualified way.
