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. Lecture videos will be posted on Moodle. Students are expected to review the recording before attending the lecture.
2. Links to recorded lecture videos, as well as complete lecture notes will be posted on Moodle. Students are expected to review these videos before the class. The class will then mainly discuss questions/clarifications with these videos, with the possibility of additional in-class exercise problems.
3. All videos are available at https://mediaspace.epfl.ch. Go to EPFL Courses, then Chemical Engineering - ChE. Here you can find the folder for the course.
4. An exercise session led by the TAs will be held during the last hour of the lecture.
5. Your smartphone would be used to conduct quizzes (usually multiple-choice questions). These quizzes are meant to support the learning process. For example, questions would 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.

Ed Discussion Forum

Questions/discussions on the concepts, in-class exercises and homework problems can be discussed on this forum. It can be accessed via Moodle.
