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.
