Summary

This course aims to provide an in-depth understanding of diffusion and mass transfer, an essential tool for the chemical engineers.

Content

 

  1. Fundamentals of diffusion
  2. Diffusion in dilute solutions
  3. Diffusion in concentrated solutions
  4. Diffusion coefficients in gases, liquids and solids
  5. Diffusion in nanoporous materials
  6. Multicomponent diffusion
  7. Dispersion
  8. Theories in mass transfer
  9. Diffusion in chemical reactions
  10. Modeling diffusion in membranes

Keywords

Diffusion, mass transfer coefficient, convection, dispersion, multicomponent diffusion, mass transfer with reaction

 

Learning Prerequisites

Important concepts to start the course

Mass, and energy balance

Basics of diffusion and mass transfer

 

 

Learning Outcomes

By the end of the course, the student must be able to:

  • Carry out calculations to extract concentration profile for a given system
  • Carry out calculations to extract mass transfer rate for a given system
  • Formalize mathematical models that describe complex mass transport cases.
  • Apply various diffusion and mass transfer models to analyze and solve a wide-range of problems dealing with mass transport.

Teaching methods

  1. Projector slides would be used to deliver the course content to the students in class.
  2. Exercise will be conducted during the lecture.
  3. Lecture notes of a specific class will be available on the moodle page (https://moodle.epfl.ch/course/view.php?id=9401).  To encourage students' participation especially on the mathematical derivation of important concepts, some notes will be excluded. A complete set of notes will be provided at the end of the class.
  4. We will use polling to conduct short quizzes (usually multiple-choice questions). These quizzes are meant to support the learning process. For example, questions could be asked at the start of every class to gauge understanding of the subject and review concepts. Your responses would be anonymous. Answers will not be used for formal assessment. To participate in the polling, you will have to install the 'TurningPoint' app on your smartphone (Android or iOS). You can find the details here:
