PSP Course 2015

PSP Course 2015

Announcement for the 6th PSP Course to be held at the DLR

 
The sixth PSP course will be held in Goettingen, Germany, from 7th to 11th of September 2015, organized by DLR in cooperation with Tohoku University, Aichi Institute of Techology, University of Hohenheim, ONERA, BAE Systems, and National Research Council Canada.
 
The Pressure Sensitive Paint (PSP) technique is a non-intrusive optical pressure measurement technique, that provides spatial pressure distributions on surfaces of e.g. wind tunnel models. It is an excellent tool for observation of spatial structures and/or rapid temporal or spatial changes of aerodynamic phenomena.
 
This course will mainly concentrate on both industrial measurement techniques as well as aspects of the theory of PSP relevant to applications with special emphasis on unsteady PSP. In addition to the lectures, participants will have the opportunity to carry out experiments by themselves during practical sessions on the course.

Purpose of the Course 

For investigations of pressure distri­butions 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 in­vestigated. 

Recently an increasing number of scientists and engineers has started to utilise the PSP technique to investigate pressure distributions in transonic, 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 sixth 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, 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.
