Objectives
To understand the mechanisms and modes of heat transfer and to identify the corresponding governing fundamental equations. The focus is on the comprehension of the physical phenomena, its mathematical modelling and corresponding hypothesys and limitations.
Learning outcomes and competences
Competences: to be able to perform qualitative and quantitative analyses in cases where relatively simple analytical solutions or correlations exist. To use quantitative analysis in design situations, through the use of appropriate calculation methods.
Results: ability to use the knowledge in the design of engineering thermal systems, valuing the approach to energy conversion processes and opportunities for the efficient and environmentally-friendly use of thermal energy.
Working method
Presencial
Pre-requirements (prior knowledge) and co-requirements (common knowledge)
Solid knowledge on Mathematics and Algebra, Thermodynamics, Fluid Mechanics, Numerical Analysis.
Good understanding of differential equations and their analytical integration.
Program
1. Introduction to Heat Transfer mechanisms and modes:
2. Conduction: steady one-dimensional conduction, fins and unsteady one-dimensional conduction
3. Convection: forced, natural and with phase change
4. Heat exchangers

Eligibility for exams
All students duly registered will obtain frequency if attaining the minimum legal number of presences in the classes (pratical and laboratory sessions).
Calculation formula of final grade
Depending on the situation imposed by the containment rules of the covid-19 pandemic, there are two possibilities: base model (plan A) or modified model (plan B).
Plan A- Base model: Distributed assessment without final exam. The evaluation of this Curricular Unit is carried out by two mini-tests, to be carried out during the semester, with each mini-test having a weight of 50% for the final grade. The first test is scheduled for mid-semester and the second will be at the end of the semester, during the exam period, to give students more time to study, although the course management will set this date. Approval for the UC presupposes a minimum average of the set of two tests of 9.5 values and a minimum score of 6.5 values for each test. The assumption of this plan is that each of the two tests, and in particular the first test, can take place simultaneously and in a single time period, for all enrolled students.
Modified model (plan B) Assessment only by final exam. If it is impossible to be able to assess according to plan A, the assessment will only be done by the final exam, and where approval requires a minimum score of 9.5.
**** Regardless of the evaluation model, the appeal test is unique and concerns the entire subject (100% weight for the final grade). The dates of all assessment tests will be defined in due course by the Course Director.
****** The special assessment tests, student workers, association directors and others, consist of a single exam covering the entire subject and with a weight of 100% for the final grade.
******* In any assessment test or test, an appropriate form will be distributed along with the statement, and no other material will be consulted. Where this regulation is silent, the FEUP general regulation applies.
NOTE 1: the exams are exclusively in Portuguese, with no translation of any exam or part of the exam into other languages.
NOTE 2: During the assessment tests (tests and exams) it is not allowed to use or be present on the test table of any type of communication device, such as mobile phone, tablet or computer, which must be turned off. It is also not allowed to use or the presence on the test table of elements of consultation that have not been previously distributed by the professors of the assessment test. The use or the simple presence on the examination table of any of these devices and elements, even if they are turned off or not being used, is sufficient cause for the cancellation of the test.
Before the test starts, and if desired, the student may deposit any device (for example, mobile phone), or unauthorized consultation elements, at a table designated by the guard for this purpose, but the team of guards cannot be assigned any liability in case of damage or disappearance of the equipment/material.
