Learning outcomes
|
The aim of the course is to provide the student with a comprehensive understanding of the solution of more complex arrangements of diffusion processes with single component transfer and selected multi-component diffusion processes.
After this course, the student is able to orient in short-cut and rigorous methods used for the selected diffusion processes. He is also able to judge conditions, which lead to simplified solutions.

Assessment methods and criteria
|
Oral examination, Written examination
Oral examination. The primary form is a debate about selected themes. The level of acquired knowledge, conceptions and application acquirements is examined. Knowledge is examined by a test during the semestr and its result is included into the total classification.
