Abstract: We developed a dual-luminophor pressure/temperature sensitive paint
(DPTSP) to correct the temperature dependence of pressure-sensitive paint. The
DPTSP is composed of two sensor molecules, PtTFPP and Rhodamine B (RhB), and
Poly-IBM-co-TFEM as a binder. Temperature was determined from the image of RhB,
and the temperature dependence of PtTFPP was corrected using the calculated
temperature. To validate the capability of DPTSP for temperature correction,
the pressure field on a delta wing model was measured by the DPTSP measurement
system. The pressure values obtained with DPTSP were in good quantitative
agreement with pressure tap data. It has been validated that DPTSP is effective
in correcting the temperature dependence of PSP.
