Course contents :
|
| This course presents an analysis of the transport phenomena at the basis of chemical engineering.
- Definitions of extensity and intensity. Concepts of mass, momentum and energy balance equations.
- Basis of fluid mechanics. Mass and momentum balance equations. Molecular and turbulent viscosities.
- Heat balance equation. Diffusional and radiative contributions. Fourier's law: thermal conductivity. Stefan-Boltzmann's law: Stefan-Boltzmann constant, emissivity. Conductive stationary heat transfer: heat transfer coefficient. Conductive transient heat transfer: Fourier's number.
- 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.
- Radiative heat transfer. Emissivity, radiativity, Kirchoff's law. Transfer between two surfaces. Radiative transfer coefficient.

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 |
|
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).
These lectures are dedicated to the detailed description of the fundamental concepts necessary for the analysis and mathematical representation of transport phenomena. |
|
Mode of delivery (face-to-face ; distance-learning) :
|
| Face-to-face |
|
Recommended or required readings :
|
| The course material is available on the eCampus website.
|
|
Assessment methods and criteria :
|
| An oral exam is organized during the first session, in June.
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 exam proceeds with closed reference books.
The second session exam is organized in the same way as in June. |
