Application of Pressure Sensitive Paint in a Compressible Flow

Abstract

Pressure sensitive paint (PSP) is used for measuring static pressure of flat plate convex corner NACA 0012 and ONERA M6 models with transonic test conditions (M = 0 64~0 92) in this study The PSP we used is composed by Ru(dpp) and silica gel which polymer content is 70% and its response time is approximately 177 5 ± 33 4 μs Because of local temperature difference this study will apply temperature sensitive paint (TSP) to measure the global temperature distribution and then correct the error which caused by local temperature difference on PSP In addition to this in-situ calibration method is used in this study after temperature correction The results are compared with the data comes from reference literature and Kulite sensors an instrument to measure the pressure It shows the root-mean-square error between PSP and reference data is almost ± 5% ~ 8% at Mach number is 0 64 and 0 7 The root-mean-square error is ± 8% ~ 10% at Mach number is 0 83 and 0 92
