Learning Objectives

The Course has the objective to train young engineers to work in industry, by providing them, through lectures, numerical exercises and laboratory experiences, specific expertise in the fields of Turbomachinery, Hydraulic Power Plants, Reciprocating Internal Combustion Engines (ICE), Power Plants for Energy Generation through Thermo-Mechanical Conversion. The student must demonstrate that he has acquired specific knowledge, with the aim of covering industrial roles in design, maintenance and management in the field of Fluid Machines and Systems for the Energy and Environment especially in the field of Renewable Energy Sources.

Course Structure

Lectures (42 hours) and numerical exercises (45 hours).

Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.

Learning assessment may also be carried out on line, should the conditions require it.
