Objectives
In this course is intended that the student acquire knowledge, skills and powers to:
- Understand the fundamental principles of conservation of mass and energy, and of conservation of linear and angular momentum to determine the operating characteristics of the different components of a facility for energy production.
- Be able to analyze the thermal engines cycles, steam and gas turbines, and the operating characteristics of the water and wind turbines more common in energy production facilities.
- Knowing the methods of selection and operation of different components of an installation of energy production from the primary actuators to the electric generators.
Subject matter
Constitution, principles of operation and characteristics of heat engines, steam and gas turbines, and water and wind turbines
In the first part are presented the principles of mass and energy conservation. These principles are applied to the study of the thermal power plants cycles (gas and steam turbines). The same principles are applied to the incompressible fluid flow. The principles of conservation of linear and angular momentum are presented, and the Euler’s turbine equation is deduced. This knowledge is then applied to water and wind turbines.

Teaching method
In the theoretical lectures the sequence points in the course program are explained and discussed, whenever possible, the resolution of a practical exercise requiring the knowledge learned in the lecture is presented.
In practical classes are presented practical exercises, whose objective is to consolidate the concepts learned in lecture, to be solved inside outside the classes. Whenever possible, laboratorial work is made.
Evaluation method
Evaluation Components:
1 - Individual work - (steam power plants)
2 - Individual work - (water turbines)
3 - Individual work - (wind turbines)
Final Grade = the average of the marks obtained in the works.
