Specific course objectives

The aim of the course “Machines” is to illustrate the main building and operating characteristics of the fluid machines of major industrial interest. Particular attention is devoted to the selection criteria of the machines, to the regulation criteria and to the interaction plant-machine in order to their optimal use. The characteristics of the main energy production plants, their fields of application, their performance and operating conditions are synthetically analyzed.
