Fluids Measurements and Design of Experiments

The theoretical and practical basics of experimental fluid mechanics will be taught in this lecture. Main topics are the methods of temperature, pressure, velocity, wall friction and density measurement using probes and optical measurement techniques (e.g., L2F, LDA, PIV, BOS). In addition to the theoretical fundamentals of the measurement methods, practical aspects are examined and visualized by demonstration and experiment. In the course of the lecture, aerodynamic test facilities of DLR will be visited and their methodology will be explained. The practice-oriented lecture is especially intended for students with fluid mechanics as major field of study.
