Abstract

When fluid mechasnical research started it became clear that measurement techniques had to be developed in order to quantify theoretical relationships deduced from observed phenomena. But also simple flow visualisation methods were developed as this was the simplest way to understand the flow behaviour when it became complex or unsteady. As an example Prandtl developed a simple water basin where the wake flow behind bodies of complex shapes could easily be observed. Also he determined basic characteristics of the wake flow. Whereas Prandtl had only his eyes and a still camera for performing his investigations today highly sophisticated optoelectronic devices are available. As a result very accurate data can be obtained within seconds although the same simulation facility is used as Prandtl applied it nearly 100 years ago. In successive lectures more examples of new powerful optoelectronic measuring methods will be discussed.
