Abstract

The present paper reports on a combined application of time-resolved stereoscopic particle image velocimetry (PIV) and planar laser-induced fluorescence (PLIF) methods to measure flow and temperature fields in a submerged swirling water jet, impinged normally on a flat heated surface. Simultaneously, the impingement surface temperature was monitored via high-speed IR-imaging. A multi-frame PIV algorithm was used to process the PIV images. A number of image filtering routines, including spatial and temporal filtering, was necessary to obtain a reliable accuracy of the temperature evaluation from the PLIF snapshots. Difference between the temperature of the liquid in vicinity of the wall and wall temperature, evaluated correspondingly from the PLIF and IR imaging, is found to be below 1°C.
