Thermal engineering is concerned with how energy is utilized to accomplish beneficial functions in industry, transportation, and the home, and also the role energy plays in the study of human, animal, and plant life.



In industry, thermal systems are found in electric power generating plants, chemical processing plants, and in manufacturing facilities. Our transportation needs are met by various types of engines, power converters, and cooling equipment.



For this subject, we start from the idea that students have already studied a basic Thermodynamics course (2nd year), a Fluid Mechanics course and a Heat and Mass Transfer course (3rd year).



This subject is one of the main subjects of the pre-intensification called "Energy Technologies", which in turn is the basis for speciality Thermo Energy Engineering Master.

In the Industrial Technology Engineering Degree, THERMAL ENGINEERING subject is within the module Optionality (M04). According to the degree memory in that module a number of basic, transversal and specific skills that are worked very generally, must be achieved.



LEARNING OUTCOMES:



Once the subject of THERMAL ENGINEERING is passed by the student, they will have acquired the following learning outcomes:



LO1: Correctly identify the problems related to thermal engineering.

LO2: List parameters for calculating and applying the appropriate resolution method developing the fundamental knowledge of thermal engineering.

LO3: To evaluate the results obtained in the development of thermal issues raised and justify its suitability from the point of view of energy efficiency, environmental or economic impact.

LO4: To be able to design and to select the equipments for thermal engineering.

LO5: Demonstrate management and computational techniques to solve problems iterative resolution applied to thermal engineering through the Engineering Equation Solver (EES) software.

LO6: Adapting the EES computer program code to new approaches to thermal problems, and interpret, recognize and correct errors that may appear in it.

LO7: Reporting to work in groups of 2-3 students in which quality criteria are applied based on the format and deadlines.

LO8: Test the consistency between experimental results obtained in the laboratory and theoretical foundations.

LO9: Express correctly orally in front of a technical audience.

The THERMAL ENGINEERING subject is designed on the 2nd part of this book: Moran, M. & Saphiro, H. Fundamentals of Engineering Thermodynamics, John Wiley & Sons. (any edition) unless the chapters 4 and 9, related to energy efficiency in buildings and applied heat technology.

M (Lecture) + GA (Problems): for lectures PowerPoint presentations will be exposed and problems for each chapter will be done on the board. The students must take notes and will be asked randomly about how they would do some parts of the problems. 30 weeks, 2 hours a week.



The student must show that the intended learning outcomes have been achieved, through the next tasks:



TASK 1: 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 2: 4 practices are performed at the laboratory. 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: Analyze a heat exchanger.

· GL2: Measure and make some calculations on a gas turbine.

· GL3: Measure and make some calculations on a heat pump.

· GL4: Analyze the behaviour of a cooling tower.

TASK 3: 6 computer classes will be done (1.5 h each one) using the ESS software 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.

· G01: problems for chapter 2.

· G02: problems for chapter 3.

· G03: problems for chapter 3.

· G04: problems for chapter 5.

· G05: problems for chapter 6.

· G06: problems for chapter 7.

TASK 4: In groups of 2-3 persons, 4 seminars for evaluation are scheduled. For each of them an oral presentation will be using made using Power Point, about the different chapters developed during the course. Those topics will be assigned randomly.

· S1: topic related to Chapter 2.

· S2: topic related to Chapter 3.

· S3, S4, S5: Energy Efficiency in Buildings. They are not for evaluation.

· S6: topic related to Chapter 5.

· S7: topic related to Chapter 6.

· S8, S9, S10: Applied Technologies. They are not for evaluation.

TASK 5: 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 6: To do the 2 exercises proposed (in each midterm), related to thermal engineering, in the written exam individually.

• Continuous Assessment System
• Final Assessment System
• Tools and qualification percentages:
  • Written test to be taken (%): 55
  • Realization of Practical Work (exercises, cases or problems) (%): 25
  • Exhibition of works, readings ... (%): 20

The evaluation system is mixed, 45% of the final grade comes from the continuous evaluation (GL+GO+S).



FINAL GRADE:



· 2 WRITTEN EXAMS (55% - They are 2 problems for each of the exams and they are evaluated through geometric mean)

FIRST MIDTERM (Sections 1 to 4) = [(Exercise 1)x( Exercise 2)]^1/2

SECOND MIDTERM (Sections 5 to 9) = [(Exercise 1)x( Exercise 2)]^1/2

WRITTEN EXAM FINAL GRADE = (FIRST MIDTERM + SECOND MIDTERM)/2

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

· REPORTS FROM LABORATORY PRACTICES (4 GL x 2,5% =10%)

· SEMINARS (4 S x 5% =20%)



- To pass the subject in the written exams a minimum of 40% must be obtained in each of the exams. If those minimums are not reached the proceedings will show the grade obtained in the worst written exam, without GL, GO and S grades. If in any of the written exams the minimum is obtained, that grade will be hold through the academic course.



- GL, GO and S grades will be the grades for all the academic course, there is no way to do them again.



- If because of holiday days any evaluable practice (seminars included) 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 (those which are missed they are apportioned).



- For certain cases (see OHARRAK/OBSERVACIONES) there is just a final evaluation system. For that system the written exams are the same as for the others, but the student must pass a seminar and one computer practice (for each of the midterms), chosen randomly by the lecturer. The value of the four practices will be 45% of the final grade (22,5% for each midterm).



- Those students who are abroad (ERASMUS or similar) for any of the semesters will be evaluated with this final evaluation system.



- To resign the exam session it will be enough just not to attend the written exam.



EVALUATION CRITERIA:



WRITTEN EXAMS:

- Identify the thermal engineering systems.

- Apply the basic concepts

- Write properly the formulae

- Mathematical developments and get results

- Critical evaluation of the results



COMPUTER PRACTICES:

- Knowledge of EES

- Apply basic concepts of thermal engineering

- Identify and correct the errors made through the programming task



REPORTS FROM LABORATORY PRACTICES:

- Take right measures at the laboratory

- Apply properly the formulae

- Delivery and formats



PRESENTATIONS OF SEMINARS:

- Format and time of the presentation

- Contents of the presentation

- Oral exposure of the presentation

The extraordinary examination will be just the written exam. In order to get the final grade, the grades of the all GL, GO and S must be added, just the same way like for the ordinary examination. So that the grades of GL+GO+S will be kept for the course, and never, and in no case, for next year.
