Abstract

This study reports a novel alternative technique that can achieve simultaneous two-dimensional temperature and velocity measurements in gas flow. This method is combining phosphor thermometry and PIV operated by a single laser unit. The temperature distribution was obtained from phosphorescence by using two-color method, and the velocity distribution was obtained from two phosphor particle images which were taken in time series during the persistence of the phosphorescence. The measured temperature and velocity were agreed with that measured by thermocouple and that expected as theoretical distribution in the high-temperature gas flows, respectively.
