- Mass and population balances. Relative displacement flux, diffusional flux. Fick's law, molecular diffusion coefficient. Transient mass transfer; Fick's number. Quasi stationary mass transfer: mass transfer coefficient.
- Convective heat and mass transfer. Stagnant film model. Surface renewal models. Dimensionless numbers. Reynolds analogy, Chilton-Colburn analogy. Correlations of matter transfer coefficients.

Learning outcomes of the course :
|
| At the end of the course, students will be able to apply theoretical concepts and the analysis methodology of transport phenomena. They will use these concepts to describe mathematically simple experimental systems. They will be able to use the formalism of mass and heat transfer coefficient.
Students will be able to link investigated phenomena to their mathematical representation and justify main simplifications adopted to develop the model
Exercise and laboratory sessions in small groups will help the students to develop more transverse skills as team-working, numerical problem resolution, critical analysis of experimental data, assessment of the validity of a theoretical approach and report writting. |
|
Prerequisites and co-requisites/ Recommended optional programme components :
|
| The courses "Chemistry" (CHIM0603-1) and "Elements of fluid mechanics" (MECA0011-2) (or courses with similar contents) should have been attended during previous years (or they should be attended the same year). |
|
Planned learning activities and teaching methods :
|
| The course is based on ex-cathedra lectures (30 h) and practical courses (30 h) including exercises and laboratory sessions.
The ex-cathedra lectures are dedicated to the detailed description of the fundamental concepts necessary for the analysis and mathematical representation of transport phenomena.
Practical courses include exercise sessions during which students learn how to solve problems related to heat and mass transport phenomena, including numerical simulation with Matlab.
During laboratory sessions, students work in (small) team. They have the opportunity to get familiar with experimental measurement techniques of fluid transfer properties.
Participation to laboratory sessions is mandatory. Each of these sessions has to be prepared by carefully reading the corresponding laboratory notes. |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| Face-to-face |
|
Recommended or required readings :
|
| The theoretical course material is available on the eCampus website.
Additional information (exercises and laboratory notes) are also available on the eCampus website at the beginning of the year.
|
|
Assessment methods and criteria :
|
| An exam is organized during the first session in June. It involves an oral part and a written part.
For the oral part, students prepare their answers on paper which they will then explain and develop orally. Evaluation relies essentially on the understanding of concepts and relationships between them rather on the capacity to make restitution.
The written part consists in an exercise to solve, which is similar to those presented during exercise sessions.
The whole exam proceeds with closed reference books. Exercise notes and formulas' lists are not accepted. Students receive at the beginning of the exam session a sheet with mathematical relations required to solve the problem.
Moreover, a report of the laboratory sessions must be provided by the students within 30 days after these sessions. This report must present the obtained experimental results, their critical analysis as well as answers to the questions presented in the laboratory notes.
The global mark is a weighted average of the marks obtained at the oral test (60 %), the written test (20 %) and the laboratory report (20 %).
The second session exam is organized in the same way as in June. The mark obtained for the laboratory report is maintained. |
