According to the verified memory of the Degree in Industrial Technology, the subject of Thermotechnics is part of the Specific Technologies module (M03). The specific competence to be developed in this subject and the expected module Learning Outcomes are as follows:



M03E1: Applied knowledge of thermal engineering.



LO1: Understanding of real problems in the Industrial Engineering environment, in any of its specialities. In addition, it is considered of special relevance that they are able to understand the importance of such a problem or failure on the industrial environment, so that they are able to make consequent decisions and do not have to regret human, environmental and/or economic losses.



LO2: Structured resolution of multidisciplinary problems in the industrial field. To this end, they are expected to design and implement industrial facilities or production and control processes.

The THERMOTHECNICS subject is designed on this book: ÇENGEL, Y. A. HEAT AND MASS TRANSFER, A Practical Approach. McGraw-Hill. 3rd Edition 2007. The subject can be divided in three big sections, depending on the mechanism of heat transfer: conduction, convection and radiation. A fourth section may be added, an introduction to mass transfer.

During the Lectures (M ) a PowerPoint will be exposed every week, in order to explain the theory of each of the chapters. To assimilate the theory, during the GAs 2-3 exercises will be made, either by the lecturer or by one student on the board, or even working in small groups.

The student must show that he or she has achieved the intended learning outcomes, through the next tasks:



TASK 1: In each subject some concept or test questions are proposed so that the student fix the basic concepts of the subject. The answers are uploaded at eGELA.

TASK 2: In each subject 2-3 exercises are proposed so that the student works individually or in group and enlarges the collection of solved problems. The solutions are given.

TASK 3: 3 practices are performed at the laboratory (one for each of the mechanisms of heat transfer). In groups of 2-3 persons, they must take some measurements in order to make the calculations and and so subsequently deliver the report.

· GL1: Measure the thermal conductivity (conduction).

· GL2: Measure and calculate the convection coefficient (convection).

· GL3: Measure the emissivity (radiation).

TASK 4: 7 computer classes will be done (1.5 h each one) using the ESS software to solve different problems previously worked during the class. During the first hour of each class the teacher will lead some exercises and in the last half hour the student will have to solve a problem by his own, which will be evaluated. That software enables to do easily parametric and design calculations.

· GO1: Fundamentals of EES software and problems for chapters 3 and 4. (This one will not be evaluated).

· GO2: Problems for CHAPTER 5.

· GO3: Problems for CHAPTER 5.

· GO4: Problems for CHAPTER 5.

· GO5: Problems for CHAPTERS 6, 7 and 8.

· GO6: Problems for CHAPTERS 8, 9, 10 and 11.

· GO7: Problems for CHAPTERS 12 and 13.

TASK 5: In groups of 2-3 persons, a speech will be made using a Power Point presentation (or similar), about a topic related to heat transfer.

TASK 6: To solve exercises from previous years. The lecturer will upload at eGELA the statements and their solutions. Some of those exercises will be done at the classroom.

TASK 7: To do the 3 exercises proposed, related to heat and mass transfer, in the written exam individually.

TASK 8: To fill a rubric to evaluate the work developed by the classmates in the GL and S.

The evaluation system is continuous, 45% of the final grade comes from the laboratory practice, computer practice and seminar (GL+GO+S).



FINAL GRADE:



WRITTEN TEST (55% - They are 3 problems and it’s evaluated through geometric mean)

COMPUTER PRACTICE ( 6 GO x 2,5% = 15%)

LABORATORY PRACTICE (3 GL x 5% =15%)

SEMINAR (15%)



TERMS:



- MINIMUM REQUIREMENT: To pass the subject in the written exam a minimum of 40% must be obtained. Otherwise the proceedings will show the grade of the written test.

- GL+GO+S PRACTICES: Any student who has taken the course in the previous academic year and wishes to keep the practices grade (GL+GO+S) must inform the course coordinator before the start of the practices in the current academic year (week 4). In the event of opting for this choice, the previous year practice grade will be taken into account for the qualification of the ordinary and extraordinary call. If the student do not want to save the grade or do not communicate it within the deadline, the unique option will be the continuous assessment or the final assessment.

- HOLIDAYS: If because of holiday days any evaluable practice is not carried out, the total percentage on the final grade will be the same. This means that the value of the ones carried out will be adjusted in order to maintain the total percentage value.

- RUBRIC: Students who do not deliver the rubric to evaluate the team work, will receive a penalty of 0.5 points. There will be also a penalty in the group grade based on the score obtained in this rubric:

· (S)he will not be penalized if (s)he gets more than 5.0.

· (S)he will be substracted 0.5 points if (s)he gets between 3 and 5 (both included).

· (S)he will be substracted 1 point if (s)he gets less than 3.

- RESIGN: The renunciation will suppose the qualification of not presented. To resign it will be enough just not to attend the written test.

- FINAL EVALUATION: The person who wishes to use the final evaluation system, thus resigning the continuous evaluation system, must notify by writing to the coordinator of the subject before 9 weeks have elapsed since the beginning of the semester. For that system the written exam is the same as for the ordinary call, maintaining the minimum requirement, but the student must pass an exam about one laboratory practice (15% of the total grade), two computer practices (15% of the total grade) and an oral presentation on a topic related to heat transfer (15% of the total grade).
