Requirements (Subjects that are assumed to be known)

Physics II

1) To provide students with well-founded knowledge of several thermodynamic processes in engineering.
2) To present from a critical perspective the principal assumptions and simplifications that lead to preliminary analyses and designs in thermal engineering.
3) To capacitate students with skills in evaluating heat transfer by conduction, convection and radiation, and to use all these abilities in the design of heat transfer equipment.
4) To be capable of characterising propulsive forces and how well the power produced by an engine is utilized in propelling an aerospace vehicle.
5) To be able to discriminate the principal parameters controlling gas turbine and internal combustion engines, and their integration in aerospace propulsion systems.

Learning activities and methodology

Learning activities in the course are based on lectures attendance, self study, problem solution, and laboratory sessions.
1) Lectures: one session per week. The instructor will provide in advance the electronic materials used in class, comprising presentation files, problem sets, property tables, bibliography, and other needed documentation. To optimise the class learning process, it is recommended to read the materials prior to each lecture.
2) Practical Seminars: one session per week attended by small groups of students. These seminars are tutorial sessions specially focused on solving problems and linking the theory with the practice. Students' questions concerning the problems will be answered by the instructor.
3) Practical laboratory work. There are four laboratory sessions aimed to make explicit what has been taught during the theoretical lectures. It is compulsory to read the laboratory guidelines & instructions before attending the sessions. After each session, a written report analysing the obtained results should be delivered to the laboratory instructor.
