Advanced Heat and Mass Transfer
Objectives and Competence
The students are able to calculate the heating and cooling time of solids such as metals, ceramics and fuels. They know the mechanism of radiative heat transfer. They know how they can influence the heat transfer by shields and secondary walls. They can apply the processes for intensive quenching using liquids. They can calculate coupled heat and mass transfer processes using equilibrium conditions. Therewith, they are able to design thermally processes for high temperature and energy process engineering.
