Year:

2025

Date/time interval

Primo Semestre (15/09/2025 - 20/12/2025)

Course Objectives

Give basic information on energy conversion systems and fluid machinery design and bahaviour.

Course Prerequisites

Thermal Physics

Teaching Methods

Lectures (about 54 hours) and exercises (about 18 hours).

In the event of provisions of the competent authority regarding the containment and management of epidemiological emergencies, the teaching may be modified from what is stated in the syllabus in order to make the course and examinations consistent with the provisions.

Assessment Methods

written + oral
Reports about exercises must be delivered at least one week before the written part of the examination. The written part consists in the solution of two exercises about fluid machinery components evaluation or design and cycles; oral part consists in the discussion af all course contents. To be admitted to the oral exam, the student has to collect at least 15/30 on the written exam. The results of written part are published on line, together with the date of the oral part. The final marks is the average between written and oral results.
