The lecture Heat and Mass Transfer II provides a deeper understanding of the mechanisms of heat and mass transfer presented in the basic lecture and builds on the knowledge conveyed there.

The students are introduced in more detail to the underlying models, which built a basis for the description of the known transport mechanisms. This includes the kinetic gas theory for the description of diffusion processes or atomic models for the description of radiation absorption / emission. In addition, the fundamentals of heat and mass transfer in multi-phase systems are presented and applied to important examples (pool boiling and film evaporation / condensation). Further focus lies on the description of heat transport at the contact of solid bodies as well as on the basics of infrared thermography. Special attention is given to the sensitization of students to simplifying assumptions, which all descriptions of natural processes are based on. The students are therefore enabled to choose appropriate models for a particular application.

The contents, specified below, are conveyed through the "Flipped Classroom" concept in the form of short online video lessons developed by the WSA in cooperation with the "Medien für die Lehre" department of RWTH Aachen University. The subjects are deepened in traditional attendance seminars in the form of lectures and exercises.
