Syllabus Information

5.1. Methodological overview

The learning process is based on the following activities:
1. Lectures, given to the entire group, in which the lecturer will explain the main concepts and procedures and will solve application problems, representative of realistic cases for the future professional practice. The participation of students, both to answer questions during the theoretical explanations as to contribute to the resolution of the exercises, will be sought. In parallel, the student must study and do exercises at home for better utilization of classes.
2. Practices of computer simulation and laboratory are distributed throughout the semester and whose assessment will contribute to the final grade. The will be performed in groups of two or three students. In advance, the outline of each practice will be distributed in Moodle. It includes a questionnaire which must be previously solved and delivered at the beginning of the session. Autonomous learning and teamwork is enhanced with this activity.
3. Tutored work individually or in small groups (ideally couples): using a software tool, students analyze and solve realistic case studies, with the advice of the teacher. Autonomous learning and teamwork is enhanced with this activity.

4. Personal work: Proposing exercises, questions and additional problems, the student is encouraged to study the matter and applying it to the resolution of the exercises. This activity is essential for the learning process and to pass the evaluation tests.

5. Academic Tutorials: The lecturer provides the student certain procedures for approach and resolving doubts. The use of these tutorials is highly recommended to ensure an adequate progress in learning. 

5.2. Learning tasks

The program offered to the student to achieve the expected results includes the following activities:
Lectures: will be developed throughout the semester, including solving problems through 3 hours per week on schedule assigned by the center. It is, therefore, an in-person activity. Attendance is not compulsory but highly recommended.  The schedule of the subject is shown in the "Program" section.

Practical sessions: 5 sessions of 2.5 h, including laboratory sessions and problem-solving sessions with computer, are planned. The student will dedicate the order of 1 h to the preparation of practice and to complete the previous questionnaire. In the laboratory sessions the student checks a given physical phenomenon and obtains experimental results which should be contrasted with the theory. At computer sessions, the student solves certain problems by numerical and graphical tools that allow treatment systems from a broader perspective.
The practices must be carried out by the student where the lecturer will encourage their participation and ability to make decisions.

Expected practices

1. Multidimensional and transient conduction. Finite difference method

2. External forced convection. Empirical estimate of convection coefficient

3. Analysis of a heat exchanger

4. Combustion: mass and energy balances. Boiler efficiency

5. Absorption refrigeration cycle. Using EES

Tutored works: Throughout the semester, in coordination with lectures and to be a complement of practices, several realistic case studies will be solved in small groups with the help of the lecturer, requiring an estimated dedication of 20 h. Materials and schedules will be posted in Moodle.

Study and personal work: This is the main part of the course, requiring about 60 hours of autonomous work, necessary for the study of theory, problem solving and preparation of the final exam.

Academic tutorials: The lecturer will publish on the website of the EINA a schedule to attend to the students in an orderly manner throughout the semester.

Final exam: EINA will plan dates of the two calls, June and September, and will publish it on the website of the EINA.

5.4. Course planning and calendar

Lectures and practice sessions are planned by the EINA. Timetables are available on the website.

Lecturer will inform about the timetable of tutoring at the beginning of the semester.
The other activities will be planned according to the teaching assignment and according to the number of students enrolled. They will be announced in advance in class and through Moodle.

Resources
Feedback between the student and the teacher will be managed through Moodle. Here the lecturer will distribute course materials (notes, questions, problems, outlines, old exams, tables, etc.), make announcements and notifications to students, send and receive emails and make available to students the tools to carry on sending reports of learning activities.

In practical activities a software tool, Engineering Equation Solver, which will be available to students through Moodle, will be used. The complete manual can be downloaded from: http://www.fchart.com/ (ADD).
