For investigations of pressure distri¬butions on wind tunnel model surfaces with high spatial resolution, new experimental techniques such as Pressure Sensitive Paint (PSP) are required. Using this non-intrusive optical pressure measurement technique, spatial structures and/or rapid temporal or spatial changes of aerodynamic phenomena (transition from laminar to turbulent flow, shocks on pitching airfoils in transonic flows, coherent structures etc.) can be in¬vestigated. Recently an increasing number of scientists and engineers has started to utilise the PSP technique to investigate pressure distributions in low speed, hypersonic and cryogenic wind tunnels, as well as in turbo machines. The PSP technique has also evolved from the measurement of steady state pressures to include both periodic and unsteady phenomena to study the instantaneous structure of pressure fields in various areas of fluid mechanics. This course, which is the fourth one on PSP organised by DLR Göttingen, Germany, will concentrate on both industrial measurement techniques and aspects of the theory of PSP relevant to applications. In addition to lectures on the fundamental aspects of Pressure Sensitive Paint Systems, special emphasis is placed on the presentation of practical and reliable solutions for problems faced during the implementation of the technique in wind tunnels and other test facilities. During practical sessions in the course, the participants will have the opportunity of carrying out experiments in small groups on paint characterisation, coating technique, and the recording and evaluation of PSP data. Recent developments of the PSP technique will be discussed and demonstrated. In addition the application of Temperature Sensitive Paint (TSP), which is from the technical point of view very similar to PSP will be part of this course.
