| FLUID MACHINERY AND ENERGY SYSTEMS
(objectives)
FORMATIVE OBJECTIVES:
The course aims to provide the students with the necessary knowledge for preliminary design and testing of thermo-electric and hydraulic power plants and refrigerators, including the thermodynamic analysis of the primary components, i.e. dynamic fluid machines and heat exchangers.
EXPECTED LEARNING RESULTS:
At the end of the course the student is expected to have the following knowledge:
- knowledge of the operating principles of thermo-electric and hydraulic power plants and refrigerators
- knowledge of the operating principles and of the basic design of turbines.
At the end of the course the student is expected to have the following skills:
- ability to calculate thermal engine systems, hydraulic motors and refrigerators
- ability to design thermal engine systems, hydraulic motors and low and medium complexity refrigerators
- ability to chose a suitable turbine for a given application
- ability to perform the basic design of a turbine
- ability to properly operate and control a turbine (power regulation, operating parameters and performance monitoring)
