COURSE DESCRIPTION

Background
This course has as objective to provide to the student the knowledge and fundamental concepts of Classic Thermodynamic, in order to establish a direct contact with the most common thermodynamic processes in the industry. At the same time, it is intended to focus on sustainable development, sensitizing students to the efficient use of energy in their professional performance. As a result of this course, students will have the tools and skills to develop and analyze in a critically way the thermodynamic processes.

It is evident that it is necessary to establish this course with a solid conceptual base since in the current teaching of engineering there is a growing interest in new knowledge that better explain the fundamental physical processes. Given the narrow time horizon and the extension of new technologies used in industrial processes, the subject matter of this course will be delivered in a very pedagogical and simple way, associated directly with the experiments that will be carried out during the course.

All phenomena involve changes in matter, and transformations of some form of energy into other forms. The judgments we can make about the ecological viability of any economic system (its sustainability) will ultimately refer to the exchange of matter and energy of that system with its environment. Hence, knowledge about matter-energy and its transformations has a big relevance for the life of human beings and the functioning of their societies.

Thermodynamics is care of the study of these transformations of matter-energy, in particular, and from its beginnings, the relations between thermal energy and work, constitutes one of the greatest achievements of the nineteenth century. Its essence is contained in two principles, known as the two laws of thermodynamics. Both can be summarize in a single sentence: The total content of matter-energy in an isolated system is constant and the total entropy increases constantly.

The Faculty of Science and Engineering of our House of Studies is convinced that the course of thermodynamics, phenomena of energy transfer, mechanics, electromagnetism, and waves are one of the keys to engineering sciences and good Performance in the professional career of our engineers. Also, the content of this course is of interest for the students who will make their memories or will be dedicated to energy, mining, soil physics, meteorology, transport of pollutants, biology, environment, and civil works.

RELEVANCE OF THE COURSE FOR STUDENT TRAINING
In practice all industrial processes require the application of the Principles of Thermodynamics. The knowledge of these principles is base in thermal engineering, for example, to carry out an energy analysis (with determination of the energy yield) of power systems for the generation of electricity (combined cycle with steam and gas turbine), an Oil refinery, a refrigeration cycle, etc.

The knowledge of whether a thermodynamic process can or cannot occur in the reality is essential for the design of new processes, as well as the knowledge of the maximum benefits that can be obtained in the different devices that compose an energy installation, and what are the causes which make it impossible to obtain these maximum benefits. The study of the thermodynamic properties of the working fluids circulating through the devices, water, air, refrigerants, gases and gas mixture, is indispensable to analyze the behavior of thermal systems. Also the study of the procedure to be followed for the energy analysis of systems of refrigeration, air conditioning and in combustion processes is of big interest.

For this reason, it is considered this course totally necessary for a comprehensive training of the current Engineer, since the study of Applied Thermodynamics gives the previous steps for the further development of Thermal Engineering (thermal power systems, refrigeration systems, Air conditioning, in addition to renewable energies); Being even necessary for the study in the fields of the transmission heat and the mechanics of fluids.

On the other hand, knowing the equations that describe the thermodynamic phenomena involved in the processes (known as mathematical models), is critical for: Combining the individual components of the plants or thermodynamic processes; evaluate the relationships between variables, subject the process to extreme conditions, among others. Today this is greatly facilitated by the availability of information technology, very sensitive instrumentation, high-speed computers and supercomputers.
