| 概要 | A lifetime-based combined measurement of temperature and velocity had been proposed in the previous studies. Temperature sensitive luminescent particles were utilized as tracer particles of the particle image velocimetry. Temperature was estimated from the luminescent lifetime of particles. In the present report, an error analysis of velocity and temperature measurement in the combined method was done by using simulated images. As results, the accuracy of velocity measurement wasn't much affected by a small displacement of particles, number density of particles, excitation intensity and its non-uniformity. The temperature estimation was relatively affected by the large displacement of particles. |
