Heat transfer

The main objective of the course is to provide the student with the knowledge of the mechanisms and laws of heat transfer, to be able to analyze the different situations in which an exchange of thermal energy takes place, as well as to calculate and design the heat exchange equipment used in the Chemical Industry.

As indicated in the degree report, the contents of teh discipline are:
1. Inrtroduction: Heat transfer mechanisms
2. Heat conduction in steady state. Insulation.
3. Heat conduction in transient state.
4. Convection: Free and forced convection, convection with phase change. Correlations for different geometries and conditions.
5. Heat exchangers: Types, calculations and design. Overall heat transfer coefficient.
6. Radiation. Boilers and furnaces.

The discipline includes a technical visit to industrial facilities related with the discipline.

The heat exchanger models in a chemical simulator (Aspen HYSYS) is included in the discipline.

Content & knowledge:
Con05: Knowledge and principles of applied thermodynamics or heat transfer and its application to solving engineering problems.

Skills:
H/D01: Teamworking
H/D02: Oral & written communication in mother languge and some foreign language.
H/D05: Capacity to apply knowledge in practical problems.
H/D09: Computer skills.

Competences;
Comp08: Capacity for problem solving with initiative, decision making, creativity, critical thinking, and knolwedge communication and transfer. Skills in the industrial engineering area.

The basic methodology will consist of lectures on the theory, with audiovisual support for the explanations, together with the resolution of related problems in seminars and the group tutorial sessions. In presential sessions a continuous evaluation will be carried out. The presence in the lectures is not mandatory and will not be evaluated.
The students will carry out 2 activities: Tests corresponding to the Introdustion chapter, and another corresponding to the Conduction chapters, at the end of teh corresponding sections (estimated: weeks 4 and 10).
Two other activities of the continuous evaluation will be:
i) A transient state problem to be solved using mathematical software (MatLab, Octave...), weeks 4/5.
ii) The study and solution of a general problem, as part of the Group Tutorial sessions: presentation of problem (week 11) and presentation of solutions by students (week 15).
Where needed, the spreadsheet used for the resolution of problems will be Excel.
In the Computer Laboratory sessions (2 h) the fundamentals of using Aspen HYSYS chemical process simulator for heat transfer equipment will be given, as support to the theory and seminars sessions. Particdipation is mandatory, in the sessions scheduled by ETSE. No participation must be justified as indicated in the USC regulations. The solution of a problem using HYSYS will be part of teh continuous evaluation.
A technical visit to a company related with the theoretical contents of the discipline will be carried out, if possible. The objective of this visit is to connect the theory with the industrial reality. D3epending on teh company schedule, it is expected in march or april.

The Learning Management System Moodle (in the web platform of the USC) will be used as repository of documentation for the discipline and communication between priofessors and students.

- Competences associated to the activities carried out:
Expositive lectures: CON05; COMP08
Seminars: CON05; H/D05; H/D09; COMP08
Computer Laboratory: H/D09; COMP08
Technical visit: COMP08
Group tutorial: CON05; H/D01; H/D02; H/D05; H/D09; COMP08

A continuous monitoring of learning will be carried out, by means of the development of different tests, activities, projects and/or resolution of problems. This continuous monitoring will be complemented with the work carried out during the tutorial sessions, also evaluated, and with a final exam, comprising theoretical questions and resolution of problems, which represents 65% of final grade. A 35% grade in each part of the exam will be necessary to pass the discipline. The contribution of each activity to the final grade is explained in Table annexed.

is mandatory to pass the discipline and cannot be recovered for the 2nd call.

Participation in the Aspen HYSYS Computer Laboratory and the exam is MANDATORY to pass the discipline. Computer laboratory due to its typology CANNOT be recovered for the second opportunity.

The qualifications of the continuous evaluation and group tutorial will be communicated to the student before the exam.

Lack of assistance/participation in any of the mandatory activities (Aspen HYSYS Computer Laboratory, the exam) will automatically produce a grade of “Not Presented” in the evaluation of the discipline. The evaluation system will be the same for the two opportunities (May and July). Marks will not be kept for other academic years.

- Evaluation of competences by activity:
Delivered problem: CON05; H/D09; COMP08
Mini-tests: CON05; COMP08
Simulation with Aspen HYSYS: CON05; H/D09; COMP08
Group tutorial: CON05; H/D02; H/D05; H/D09; COMP08
Exam: CON05; COMP08

- Evaluation system:
Activity; % grade; Minimum grade (if applicable, minimum % on the activity evaluated); Requisite)
Delivered exercises; Simulation with Aspen HYSYS (Compulsory); Mini-Tests; %calif: 20%.
Group tutorials; %calif: 15%.
Exam: %calif: 65% (min. 35% each part)

In case of fraudulent procedures during the evaluation activities, the University rules for evaluation of academic performance of students will be applied.

A total of 150 hours (6 ECTS credits) of work by the student, including class time, are estimated. Out of this total, 53 hours will be in the classroom in the form of expositive, interactive and tutorial lectures.

It is advisable to have previously taken courses of Mathematics and Applied Thermodynamics, as well as to have a good basis of mass and energy balances.

It is recommended the adquisition of computers with the MS Windows operative system, since other systems do not support the chemical process simulator software Aspen HYSYS.

Teaching is conducted in Spanish, although any sources of information will also be handled in English in Transmisión de Calor and in English in Heat Transfer.
