TU Ilmenau

Teaching

The Department of Aerodynamics of the Institute of Thermo- and Fluid Dynamics is responsible for the education of mechanical engineering and mechatronics students in the basic subject Aerodynamics and for the specialization subject Heat Transfer 2.

Both lectures are one-semester elective courses in the Master's degree program in Engineering Sciences comprising 4 SWS (2 SWS lecture + 2 SWS seminar) MB_MA in module SW5.

Winter semester

Ronald du Puits

Lecture on heat radiation

Why is the warmth of a tiled stove more pleasant than that of central heating? Why does a green laser pointer appear brighter than a red one? Why does an incandescent lamp produce so little light? How does a pyrometer work?

These and other questions of heat transfer by radiation are to be answered in the lecture Thermal Radiation. In addition to imparting basic knowledge, the focus is on engineering calculation methods and the industrial application of radiation sources. Basic knowledge of thermodynamics is a prerequisite for understanding the lecture.
