Status of the course

Course objectives

Gaining knowledge about the principles of transfer of momentum, heat and mass transfer on the principle of a unified approach to transport phenomena. This knowledge forms the basis of chemical engineering unit operations, and they are therefore essential for a fuller understanding of process engineering.

Course enrolment requirements and entry competences required for the course

Enrolled in or passed the course Exercises in Transport Phenomena

Learning outcomes expected at the level of the course (4 to 10 learning outcomes)

After passing the exam the student is expected to know:
- how to apply the laws of conservation of the fluid flow
- about molecular and convective mechanisms of transport of momentum, energy and mass
- how to recognize the major resistance at transport phenomena and how to intensifying the observed transfer
- how to gain insight into the functional dependence of the characteristics of a given system by the use of similarity theory and dimensional analysis
- the analogy of transfer of momentum, energy and mass
