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. In particular, 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. Furthermore, 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)
EXPECTED LEARNING RESULTS: Knowledge and understanding: Understand the fundamental principles associated with the preliminary design and testing of thermo-electric and hydraulic power plants and refrigerators. Applying knowledge and understanding: By carrying out case studies, the student will be encouraged to develop an applicative skills on the methodologies and techniques acquired. Making judgments: To be able to apply the acquired knowledge to solve simple problems in the field of the preliminary design and testing of thermo-electric and hydraulic power plants and refrigerators. Communication skills: Knowing how to explain, both in written and oral form, the problem and the possible solutions of simple situations concerning preliminary design and testing of thermo-electric and hydraulic power plants and refrigerators. Learning skills: Knowing how to collect information from textbooks and other material for the autonomous solution of problems related to the applications of preliminary design and testing of thermo-electric and hydraulic power plants and refrigerators.
