The subject "Thermal Engineering" constitutes the basic subject to address with guarantees a solid training in energy issues. It is taught in the second year of all Engineering degrees, forming part of the "Common to the Industrial Branch" module and is essential for addressing the "Mechanics", "Electrical" and "Industrial Electronics" modules.



The contents of the subject will deal with two main blocks, Technical Thermodynamics and Heat Transmission. The basic principles of Thermodynamics applied to the processes, cycles and systems of conversion of energy into heat and work will be studied, as well as the laws that govern the mechanisms of heat transfer by conduction, convection and radiation, and their applications in heat exchangers.



As a subject in which the processes and systems of conversion of heat into work and vice versa are studied, it is linked transversally with the subjects of Fluid Mechanics and Applied Mechanics, and constitutes the basis for subsequent subjects such as "Technology for Renewable Energies", "Power Stations and Renewable Energy ", and "Thermal Machinery and Facilities", of the Degrees in Electrical Engineering, Degree in Electronic and Automatic Engineering and Control and Degrees in Mechanical Engineering.



In Thermal Engineering, thermodynamic substances, thermodynamic processes, transfer processes and systems, engines and thermal machines are studied; For this, you must learn to model these substances, applying various mathematical models to calculate their properties, you must learn to graphically represent the block diagrams that usually represent in engineering the various systems and devices such as turbines, compressors, valves, boilers , heat exchangers, etc. and one must learn to apply balances of mass, energy, entropy and exergy. To address all this, knowledge about first-year subjects such as "Calculus", "Physical Basis of Engineering" and "Chemical Fundamentals of Engineering", but also about "Technical drawing " and "Algebra" is very necessary.



It also involves presenting various real-world engineering applications to give students insight into the practice of thermal engineering and develop an intuitive understanding of the subject, emphasizing the thermodynamic study of the physical phenomena involved.

The objective is to train the student in the knowledge of the principles of Thermal Engineering for its implementation in practical cases, enabling him to solve problems related to Thermal Engineering.



The skills that the student must acquire at the end of the course will include knowledge of Applied Thermodynamics and Heat Transmission, in terms of its basic principles and their application to solving engineering problems, and applied knowledge of thermal engineering.



The specific competences of the subject are the following:



Competence 1: Know, understand and apply the basic concepts of Thermodynamics applied to processes and systems of transformation and exchange of energy that allow the student to face more technological studies in depth on machines, motors and industrial thermal processes in which a understanding and skill in the approach of energy balances and the equations that describe the thermodynamic transformations that work substances undergo.

In this subject, an active methodology based on flipped learning is used, supported by a thematic YouTube channel with video tutorials on the contents of the subject, the application of the concepts developed through a Guided Problem Solving methodology. and a test-based formative assessment to be done in class using the Socrative platform. The teaching modalities are completed with classroom, computer and laboratory practices.



In the lectures, the concepts of the subject will be presented, with the active participation of the students by raising questions, exchanging ideas and occasional debates on the daily application of these concepts and their implications. The schedule is based on the contents of the books “Fundamentals of Technical Thermodynamics” and “Heat and Mass Transfer. A practical approach”.



The problems developed in the classroom, computer and laboratory practice hours serve to reinforce the theoretical concepts acquired in the master classes, and are always related to everyday situations, current cases and industrial processes and applications. Debate is encouraged between students, and with the teacher, regarding the problems proposed in relation to how to solve them and the consequences that derive from the adopted solution. Although it is a subject that is taught in the second year, it is necessary for the student to acquire a way of thinking and a way of solving problems that allows them to have a global vision of the problem considering technical, economic, ethical, environmental aspects. of innovation, etc.



Tasks to perform:



Theoretical concepts are explained in the master classes every week, using the support considered most appropriate: PowerPoint presentations, videos, spreadsheets, etc. All the material used is made available to the student through the eGela platform. The theoretical contents are reinforced in weekly classroom practices, in which the teacher performs the exercises on the blackboard with the help of the students, some students with the help of the teacher and the rest of the students, or working in groups.

The student must perform a series of tasks to achieve the expected learning outcomes.



TASK 1: In each topic, the teacher proposes a series of problems, providing their results. By solving the problems, and having the results available, the student can self-evaluate, in such a way that they can assess their need to work more on certain concepts and sections of the subject. All this, taking into account the possibility of attending tutorials to clarify possible doubts about problem solving, in such a way that the teacher himself can guide the student in the learning process.



TASK 2: Four computer practices are proposed in which each student must computationally solve exercises similar to those developed in class. Different variants of the same exercise are prepared, in such a way that the exercise is the same for all students, but the starting data is different to avoid copying. It is considered positive that students help each other, as it improves relationships and also enhances the learning process. The students know, before going to the practices, what is going to be developed in them, which allows them to prepare them before each session is held.

The qualification of the practice is published in eGela within a maximum period of 2 weeks. Possible doubts regarding the resolution of the exercises are done in tutorials for each student, if errors are detected that indicate that some concept has not been correctly assimilated by the group of students, the master class is used after the day of publication of the qualification to reinforce the concepts.



TASK 3: 3 laboratory practices will be carried out in groups of 3-4 students. The procedure consists of measuring a series of variables, performing the necessary calculations to obtain the necessary results to describe the behavior of the equipment, critical commentary on the results, and finally proposing improvements to its operation.

Students will submit a written report within the deadline set by the teacher. This report will include the assessment they make of their work in the group and that of their peers. The corrected and commented report will be returned within a maximum period of 2 weeks in order to guarantee feedback.



TASK 4: Solve the exam problems from previous years. The teacher makes available to the students the resolved exams from other years. In this way, the student knows the level that is required in the final test, how to solve the problems (problem solving procedure in Thermal Engineering) and if he is qualified to face it.

• Final Assessment System
• Tools and qualification percentages:
  • Written test to be taken (%): 55
  • Realization of Practical Work (exercises, cases or problems) (%): 45

The evaluation of the subject will consist of a final written exam, consisting of solving problems and/or theoretical questions, with a value of 55% of the final grade, and laboratory and computer practices with a value of 45% of the grade. final.



Occasionally, the student who cannot attend a practice for any of the reasons justified in the regulations, must change the schedule assigned for said practice with another student and notify the teacher well in advance.



Students who cannot attend practices at the established time, should contact the Center Management to notify them and find a solution if appropriate. Teachers do not have the power to establish such schedules.



To pass the subject, in the written exam to be developed, a minimum of 40% of the maximum mark obtainable in the exam will have to be obtained. The written exam grade will appear in the minutes if the minimum required is not reached.



Likewise, it will be necessary to obtain a minimum score in each exercise of the written exam equal to 25% of the maximum mark for said exercise. Otherwise, the mark for the written exam will be a maximum of 25% of the maximum mark obtainable in the exam.



If any of the evaluable practices are not carried out due to holidays, this practice will not be carried out and the practices carried out will be prorated so that the weight of the practices continues to have the corresponding weight of the final grade.



The student must appear in person at the exam with ID or original passport.



In compliance with art. 39 of the Regulations for the Management of 1st and 2nd cycle Teachings and since the value of the final test scheduled is 55%, not taking said test will mean renouncing the call and will be classified as NOT PRESENTED.



In compliance with art. 8 of the Regulations Regulating the Evaluation of Students in Official Degrees, in any case, students will have the right to be evaluated through the final evaluation system, regardless of whether or not they have participated in the continuous evaluation system. To do this, students must submit in writing to the teaching staff responsible for the subject the waiver of continuous assessment, for which they will have a period of 9 weeks for four-month subjects.



Students who renounce continuous assessment must take a final test (with a value of 45% of the final grade) that will consist of the evaluation of this part of the subject (the one evaluated through continuous assessment), in addition to the final exam. written (with a value of 55% of the final mark). These students must meet the same conditions as the students who do not renounce continuous assessment to pass the course:



- In the written exam you must obtain a minimum of 40% of the maximum mark obtainable in the exam.



- It will be necessary to obtain a minimum score in each exercise of the written exam equal to 25% of the maximum mark for said exercise.



This final test will be held after the final written exam.

The extraordinary evaluation of the subject will consist of a final written exam, consisting of solving problems and/or theoretical questions, with a value of 55% of the final mark, and a final test of laboratory and computer practices with an assessment 45% of the final grade.



To pass the subject, in the written exam to be developed, a minimum of 40% of the maximum mark obtainable in the exam will have to be obtained. The written exam grade will appear in the minutes if the minimum required is not reached.



Likewise, it will be necessary to obtain a minimum score in each exercise of the written exam equal to 25% of the maximum mark for said exercise. Otherwise, the mark for the written exam will be a maximum of 25% of the maximum mark obtainable in the exam.



The final practice test of the extraordinary call will be held after the written test.
