Abstract
The knowledge of highly unsteady flow phenomena and acoustics is important in order to comply with tightening environmental regulations and increasing comfort levels. To investigate the broad band and tonal noise as well as unsteady flow iPSP measurement system is employed. iPSP is an optical measurement system which consists of fast response Pressure Sensitive Paint applied to a surface, a high power illuminator to excite the paint and a high speed camera to measure the paint emission light which is dependent on the pressure levels. In this presentation two applications are shown. One for the acoustic measurement with iPSP and another for measurements in TWG in a cavity at transonic and supersonic Mach numbers.
