| Research Abstract |
A combined measurement technique of velocity and temperature distribution in a fluid flow was developed. Particle image velocimetry was combined with a lifetime based scalar measurement technique. Developed method needed a high speed camera, a single-pulsed UV laser and temperature sensitive particles. The method was applicable to any kinds of working fluids and to the wide range of temperature. The temperature and the velocity were estimated from common images. We built a database of optical properties of luminescent materials, such as temperature dependency of the lifetime, spectrum and emission intensity. The developed technique was applied to measure the temperature and velocity of the gas flow in the cylinder of the optical engine.
