The velocity field and temperature distribution in a fluid flow were measured simultaneously based on luminescence. PIV is useful for velocity measurement, and a measurement method based on the luminescent lifetime is appropriate for detecting the transient temperature field. In the present study, particles doped with EuTTA, called temperature sensitive particles (TSParticles), were prepared. The optical properties of the TSParticles were investigated. TSParticle was found to be suitable for use with an optical sensor because its lifetime is very sensitive to temperature changes. The lifetime of the TSParticle was approximately 600μs at 20℃ in water and the intensity was also large enough to be detected by a CCD camera without any image intensifier, at an exposure time of less than 60μs. It was found that TSParticles could also be used for velocity measurement by means of the PIV technique. The temperature field was measured based on the decay ratio of the TSParticle images, and the velocity distribution in the same plane was also evaluated from these images by PIV. A demonstration was carried out in a thermal stratified silicone oil bath. The velocity and the transient temperature distribution of the oil flow were successfully measured.
