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.
It is given a special emphasis to the critical thinking in the analysis of problems which students come across during the semester. The learning outcomes are the identification of mechanisms, and the determination of the rate at which heat and mass transfer occur in different situations.
Students will be stimulated to survey printed and electronic literature in English, as well as working in a team, this component being taken into account in the assessment.

 

Learning outcomes and competences

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

Skills acquisition - application of critical thinking to solve engineering problems involving heat and mass transport, knowledge integration,  teamwork stimulation.

 

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Pre-requisites: basic backgorund on Mathematical Analysis and Thermodynamics.

Program

HEAT TRANSFER
1. Introduction: Heat transfer vs. Thermodynamics. Heat transfer mechanisms: conduction, convection and radiation;
2. Steady state heat conduction transfer;
3. Non-steady state heat transfer;
4. Convection heat transfer: thermal boundary layer; correlation to calculate convective coefficients in Newtonian fluids. Application to heat exchange systems.
5. Summary Notes on Radiation Heat Transfer.

MASS TRANSFER
5. Mass transfer fundamentals: molecular diffusion; Convection and its effects on diffusion; Non-steady state mass transfer;
6. Mass transfer and reaction (simple cases); Mass transfer in gas-liquid and solid-fluid systems (simple cases);
7. Simultaneous mass and heat transfer;

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 is composed by theoretical-practical classes (two of 90 min each and one of 1 h, per week) where the theoretical concepts and their applications will be presented, together with the dscussion of illustrative problems.
Students will get practical problems to solve, so that they can practice OUTSIDE class time. Professors will be available to help students solve those exercises.

 There are also laboratorial classes where an average of one hour/week is devoted to the subject matters of this course.

Eligibility for exams

To be admitted to exams, students have to attend classes.

 

Calculation formula of final grade

The Final Grade will be based on two components: 

1) CONTINUOUS ASSESSMENT:
1-A) Home work assignements (25% of the final grade) - 1 problem of Heat Transfer , 1 problem of Mass Transfer. These problems are solved in teamwork, oustide the classes (each team is composed of 2 students).
1-B) Laboratory work (25% of the final grade) - carried out in the specific lab classes.

2) EXAM: 50% of the final grade .

All the Exams (in the "Normal" period, "Repetition" period or "Special" period) cover all the subjects of the course. The duration of the Exams is 3 hours.

IMPORTANT COMMENT: Students have to reach a MINIMUM grade of 8 in the EXAM component  and, furthermore, they have to reach also a MINIMIUM grade of 4 on each one of the 2 parts of the course programme (Heat Transfer AND Mass Transfer).

The final grade is given on a scale from 0 to 20.
