A109 流体計測のための担持型TSPの開発とPSPへの応用

抄録

In the present paper, current status of the development of luminophore-pendant temperature-sensitive paint of poly [1-(trimetylsilyl)phenyl-2-phenylacetylene] (PTMST) is discussed. PTMST uses poly(1-trimethylsilyl-1-propyne) (PTMSP) based polymer, which is known as one of the highest gas permeable polymer. We mix platinum tetrakis(pentafluorophenyl) porphyrin (PtTFPP) as a pressure-sensitive luminophore to create PTMST-based two-color PSP (PtTFPP-PTMST). We have calibrated PTSMT itself from 100K to 373K as well as PtTFPP-PTMST from 120K to 333K to study the static characteristics of these sensors. PTMST provides the temperature sensitivity over the calibrated range. PtTFPP-PTMST shows pressure sensitivity even at cryogenic temperature (120K). The unsteady characteristic of response time of PtTFPP-PTMST is determined to be on the order of milliseconds by using a shock tube. A demonstration of PTMST at cryogenic measurement is shown from transition detection on PTMST coated NACA64A012 model in JAXA 0.1m Transonic Cryogenic Wind Tunnel.
