Thermal Processing/ Heat Technology
Master courses
Environmental engineering and energy process engineering , safety and security
Objectives of modules
The students calculate the heating and cooling processes of solids such as metals ceramics and fuels. They know the mechanism of heat transfer by radiation. They know how to influence heat transfer by radiation shields and secondary radiation. You can apply the methods of intensive cooling with liquids. They calculate coupled heat and mass transport processes using equilibrium equations. They are able to interpret thermal processes of high temperature process engineering and energy technology .
