A- Identify the different forms of energy (Primary and final energy).

B- Acquire scientific bases of the production and conversion of Energy.

C- Apply the basic principles of thermodynamics and thermotechnics and their application to solving energy engineering problems.

D- Understand the principles and objectives of the different energy transformation strategies with high efficiency (Engines, turbines, co-generation, renewable energies, energy policy ... etc).

E- Develop skills to solve practical problems.



The main learning outcomes, based on tasks or activities that the students should be able to develop after completing the course, are specified below:

• Identify the different forms of primary and final energy and understand the thermodynamic principles for the conversion of primary energy into final energy.

• Understand and interpret energy balances.

• Perform material and energy balances in combustion facilities. Calculate fuel consumption and the quantity and composition of combustion gases.

• Know the physico-chemical properties of solid, liquid and gaseous fuels as well as the calculation methodology of the upper and lower heat of combustion.

• Understand the thermodynamic cycles for the production of electric power in power plants with steam turbines and gas turbines.

• Design power plants with steam turbines and/or gas turbines: calculation of fuel requirements, selection of working fluid, inlet pressure to the turbine, condenser pressure, calculation of the thermal efficiency of the plant.

• Understand the strategies for increasing thermal efficiency: cogeneration and combined cycle.

• Know the thermodynamic cycles for the production of mechanical energy in internal combustion engines.

• Classify and understand the technology for the use of renewable energies.

In order that the students can acquire the specific competences previously exposed, three different types of teaching modalities have been programmed: theory classes, practical classes and seminars. In the theory classes (T) the teacher presents the student with a summary of the topic in which it will include the fundamental objectives and concepts and information on material to prepare the topic. In the practical classes (GA) problem solving and/or questionnaires will be shown to apply the acquired knowledge. Those classes will be interactive, which allow discussing different resolution methodologies, identifying advantages and disadvantages of each of them. The seminars classes (S), will be held in smaller groups, to provide a working group environment and facilitate the discussion of doubts. Here, more personalized tasks will be programmed and analyzed according to the needs of the student. In addition to the domain of knowledge, competences on oral expression and synthesis and reasoning skills will also be evaluated. The seminars will also be used to review and share tasks assigned during the course to strengthen the concepts worked on. In general, in the planned activities, the student must be involved in processes of information search, analysis and critical reasoning.

There are two evaluation methodologies: i) continuous evaluation, and ii) final evaluation. In the continuous evaluation, students must complete the tasks scheduled during the course, with the following percentages of qualification: resolution of individual tasks (10%), team project development (10%), group work with oral presentation (10 %) and individual written examns (70%). Two individual written exams will be carried out during the course, the first one in the middle of the semester and the second during the last teaching week. In order to be able to pass the subject in continuous evaluation, it is required to obtain a minimum grade of 4.0 in each of the individual written exams. Fulfilling this criterion, a minimum grade of 5.0 is required to PASS the subject in its continuous evaluation modality, taking into account the qualification percentages above detailed. In the case of not having obtained a minimum grade of 4.0 in any of the individual written exams, students will have to take a final written exam on the official date established for the ordinary examination session. The qualification of the subject will be made according to the percentages of qualification previously described. A minimum grade of 5.0 is required to PASS the subject.

Students can be evaluated through the final evaluation system, regardless of whether or not they have participated in the continuous evaluation system. For this, students must communicate to the teacher the renouncement to continuous evaluation, for which they will have a period of 9 weeks from the beginning of the subject, according to the academic calendar of the center.



Although being part of the continuous evaluation methodology, not taking the ordinary final exam of the subject will lead to a calification of NOT PRESENTED.

The content of this section will be detailed in eGela on-line course.
