The module aims at supplying the fundamentals of fluid-flow machines, with specific reference to constructive aspects, principles of operation, evaluation of performance and off-design operations of both the single fluid-flow machine and the energy system in which it is inserted.
Through the systematic application of the principles of thermo-fluid-dynamics to energy conversion systems and their components, the module provides the students with the ability not only to choose engines and engineering-plant solutions in relation to their applications, but also to approach and solve specific design problems by integrating the concepts acquired in the module with advanced notions on specific topics.

The exam booking on the web portal, within the deadline, is mandatory.
The exam is made up of a written part and of a oral part. The final mark is a weighted average of the written part and oral part marks, the weights being 2/3 and 1/3, respectively.

In order to be admitted to the oral, each candidate needs at least a mark of 15/30 from the written test. Both exam parts have to be taken within the same call.
