Objectives

This course unit aims to develop students’ skills in the interpretation and quantification of heat and mass transfer phenomena, with applications both in biotechnological industrial systems, in the environment and in the human body. A background of Mathematical Analysis and basic Thermodynamics is needed.
A special emphasis is given to the critical thinking in the analysis of problems which students come across during the semester. The learning outcomes include the identification of mechanisms, and the determination of the rate at which heat and mass transfer occur in different scenarios.
Students will be stimulated to use technical literature in English, as well as working in a team, this component being taken into account in the assessment and in the laboratory work.

Learning outcomes and competences

Learning Outcomes - solve problems involving heat and mass transport, design of simple heat and mass transfer systems.

Program

HEAT TRANSFER
1. Introduction: Heat transfer vs. Thermodynamics. Heat transfer mechanisms: conduction, convection and radiation
2. Steady state heat conduction and convection
3. Unsteady heat transfer
4. Heat exchangers
5. Brief notes on Radiation Heat Transfer

MASS TRANSFER
6. Mass transfer fundamentals: molecular diffusion; Convection and its effects on diffusion; Non-steady state mass transfer
7. Mass transfer and reaction (simple cases); Mass transfer in gas-liquid and solid-fluid systems (simple cases)
8. Examples: Heat transfer in skin burns; heat transfer in landfills; milk pasteurization; temperature profiles in solid food sterilization; effects of convection, radiation and transpiration on maintaining body temperature; biological reactors mass transfer; artificial system of blood oxygenation; artificial kidney/haemodialysis; supervised release of drugs

Teaching methods and learning activities

This course unit includes theoretical-practical classes in which the theoretical concepts and their applications are presented, together with the discussion of illustrative problems.
Students will receive practical problems to solve, which they can work on at home, with professors available for assistance.
Additionally, there will be laboratory classes that complement the course topics.

Calculation formula of final grade

The assessment of the curricular unit will consist of two tests or a final exam, a project on Mass Transfer, in addition to the mandatory laboratory component:

Test 1 (Heat Transfer) - To be held in November (date to be announced in advance), covering the content from the Heat Transfer component. 

Test 2 (Mass Transfer) - test on the Mass Transfer component, to be taken by students who scored 8/20 or higher in Test 1. This test will take place on the same date as the regular exam. 

Homework (Weight: 10%) - Mass Transfer project, to be done in groups of 2 students. This project is mandatory.

The final grade (CF) will be calculated as follows:

CF = 0,25 x LAB + 0,10 x TPC + 0,375 x NT1 + 0,275 x NT2             (Eq. 1)

where:
- LAB represents the grade for the laboratory component (scale 0-20)
- NT1 and NT2 represent the grades of Tests 1 and 2, respectively (scale 0-20). NT1 and NT2 have both a minimum grade of 8 (out of 20)
- TPC represents the grade of the Homework (Mass Transfer; scale 0-20).

If the grade obtained in Test 1 is below 8/20, instead of Test 2, the regular exam will be taken, covering both heat and mass transfer components. In this case, the final grade will be based on the laboratory component (LAB), the homework, and the grade obtained in the regular exam:

CF = 0,25 x LAB + 0,10 x TPC + 0,375 x EX_C + 0,275 x EX_M              (Eq. 2)

where EX_C corresponds to the grade for the Heat Transfer component of the exam, and EX_M corresponds to the grade for the Mass Transfer component of the exam. 

Alternatively, students can take the resit exam (covering both Heat Transfer and Mass Transfer components). The final grade will be calculated using Eq. 2.

Students who scored above 8/20 in Test 1 have the option to take the regular exam instead of Test 2, covering all the content of the curricular unit. In this case, the final grade will also be calculated using Eq. 2.

The resit exam (as well as special exams) will encompass all content covered in this curricular unit. The grade will be calculated based on Eq. 2.

Students who have successfully completed the laboratory component in previous academic years are not required to repeat it and will retain their laboratory grade (LAB).
