Flat plate film cooling measurement using PSP and gas chromatograph techniques
Abstract
The use of pressure sensitive paint (PSP) to measure film cooling effectiveness is demonstrated in a high speed wind tunnel using a flat plate. To validate this technology, gas chromatography was used to measure film cooling effectiveness from the same plate. Four (4) blowing ratios 0.5, 0.75, 1.0 and 1.5 were tested using the two methods. The flow stream turbulence effect was not studied and the free stream turbulence intensity was fixed at 4.0%. The PSP was calibrated at various temperatures as well as at various pressures before testing. The test results on the flat plate indicate that the PSP method of measuring film cooling effectiveness is far superior than the traditional gas chromatography method. The better spatial resolution and two dimensionality of the pressure sensitive paint method offers a great potential for its application in film cooling measurements.
