Exposure to typical experiments, diagnostics hardware, data acquisition and processing. Study of applications in the laboratory. Fundamentals of scientific documentation & reporting. | ||||
| Inhalt | In-class introduction to representative measurement techniques in the research areas of the participating institutes (fluid dynamics, energy technology, process engineering) Student participation in 8-10 laboratory experiments (study groups of 3-5 students, dependent on the number of course participants and available experiments) Lab reports for all attended experiments have to be submitted by the study groups. A final exam evaluates the acquired knowledge individually. | ||||
| Skript | Presentations, handouts and instructions are provided for each experiment. | ||||
