Prerequisites: General knowledge of Fluid Mechanics, Applied Mechanics and Thermodynamics.
Target skills and knowledge: Basic principles of energy conversion in different types of fluid machines such as internal combustion engines, positive-displacement pumps and compressors, centrifugal and axial pumps and compressors; application areas of the different types of fluid machines and criteria for their selection; preliminary design procedures.
Examination methods: The preliminary design of a fluid machinery, to be carried out as homeworks during the course, involves the preparation of a technical report and the execution of technical drawings of machine components, to carry out individually, although the student can cooperate within a team consisting of no more than 3-4 students.
The preliminary design contributes about 30% of the final grade, while the remaining 70% is given by the oral examination.
The oral exam typically involves three questions about the entire course syllabus, and takes about 45 minutes.
The oral examination is done in Italian.
Assessment criteria: Fluid machinery preliminary design:
- The correctness of the general approach.
- The accuracy of the methodology for calculating and verifying the results.
- The appropriateness of the technical terminology adopted.
- The overall quality of the proposed fluid machinery preliminary design.
Oral exam:
- Knowledge and understanding of the teaching course contents;
- ability to describe the fluid machinery fundamental principles and performance;
- criteria for selecting proper types of fluid machinery and energy conversion system configuration;
- Simple problems of preliminary sizing of fluid machinery components;
- Ability to discuss the topics in a clear and concise way, with a proper use of technical terminology;
- Time elapsed from the end of the classes and the date of the oral exam
Course unit contents: Basic concepts of energy, energy sources and different types of energy conversion systems and machines.
Volumetric fluid machines: reciprocating pumps and compressors, positive-displacement rotary pumps and compressors, application areas and criteria for the selection of the pump or compressor type; preliminary projects.
Fundamentals principles of turbomachinery: energy exchange in turbomachines, internal energy loss sources, mechanical similitude theory and compressibility effects; application exercises.
Centrifugal and axial pumps: application areas and criteria for their selection, characteristic curves, impeller, diffuser and volute, preliminary projects.
Fans, blowers and compressors: centrifugal and axial configurations, application areas and selection criteria, characteristic curves, surge and rotating stall, impeller and diffuser apparatus, preliminary projects.
Internal combustion engines: engine operating cycles, two-stroke and four-stroke engines, engine mixture requirements, spark-ignition engines, compression-ignition engines, supercharging, engine operating characteristics performance; application exercises.
Planned learning activities and teaching methods: Traditional teaching methods complemented by laboratory practices.
Application areas of the different types of fluid machines and criteria for their selection; design procedures and preliminary design examples.
Additional notes about suggested reading: Lecture notes.
