Learning outcome

After this course the student can:

- Identify and describe transport phenomena dominating processes in metallurgical and electrochemical systems.

- Explain various aspects regarding transport/transfer of mass, momentum, energy, and chemical components in fluid mixtures or between phases.

- Perform basic computations on transport/transfer of mass, momentum, and energy in idealized (sub-)systems, e. g. by application of boundary layer theory or correlations for energy and mass transfer.

- Choose necessary actions for incorporation of chemical reaction kinetics as well as treatment of particles, droplets and bubbles in the overall global conservation equations for mass, momentum and energy.

- Identify and describe electrochemical reaction rates, and how these relate to current and voltage in electrochemical cells

- Formulate and analyze problems involving radiation in multi-surface systems.

- Use methods for finding and evaluating estimates based on dimensional analysis and analogies for heat and mass transfer.

- Introduce simplifying assumptions for computations and assess the validity of the simplifications done.

- Perform calculations of electrochemical cells with coupled kinetics and transport phenomena.

- Set up and interpret simple numerical simulations in heat and mass transfer related problems.

Learning methods and activities

Lectures (60 hours), exercises (30 hours) and self study (120 hours).

Lectures will be given in English and examination papers will be given in English only, while students can choose to use Norwegian or English during the oral examination and/or presentations.

50% of the exercises must be approved before the final exam as well as a written report relating to numerical simulations of heat and mass transfer.

The report will serve as a basis for an oral presentation which will account for 30% of the final grade. The presentation must be approved in order to qualify for the final exam.

Students are free to choose Norwegian or English for written assessments.

Compulsory assignments

• Report
• Exercises

Further on evaluation

Course evaluation:

Oral presentation based on report counts for 30% of the collective grade. An oral exam counts for 70% of the grade. Both exams gives an individual grade, and will be combined for the final grade in the course.

• Re-sit exam in august
• You can improve your grade in both grades, or just one to improve your grade in the course

Mandatory assignment:

• Mandatory assignments in the course can be used when retaking the course
