Abstract
This study presents a novel alternative technique that can achieve simultaneous two-dimensional temperature and velocity measurements in the gas flow. This method is combining phosphor thermometry and PIV operated by only one laser. The temperature distribution can be obtained from phosphorescence by using two-color method, and the velocity distribution can be obtained from two phosphor particle images which taken by the camera system in time series during the persistence of the phosphorescence. The measurement was demonstrated in two flow cases, i.e. a free jet and a impinging jet. The measured temperature and velocity were agreed with expected jet flow and impinging jet distribution, and also measured temperature showed qualitative conformance to the temperature measured by thermocouple.
