Learning assessment

The exam includes the verification of the level of achievement of the previously indicated training objectives. The exam is divided into two parts:
- a written test to assess whether the student has learned the basic principles for evaluating the performance of fluid machines and energy conversion systems. The test includes exercises: i) performance estimation of a power plant thermodynamic cycle (gas turbine or steam power plant reciprocating engine); ii) performance estimation and design of an expansion stage (including velocity triangles and blades representation); iii) performance estimation of reciprocating engines, pumps or compressor.
- an interview in which the level of knowledge and the ability to present the topics covered during the course will be assessed. The interview will consist of at least three questions on thermodynamic topics applied to the study of energy conversion plants; fluid dynamics of turbomachinery; internal combustion engines.
The aim assessment of the written test is aimed at admission to the interview and will be considered passed if at least two of the three exercises have been carried out correctly. The final evaluation will take into account the correctness of the exercises carried out, the correctness and the quality of representation of diagrams, schematics and figures; of the correct use of symbols and formulas; of the ability to exhibit and master the topics.
