The application of stereoscopic PIV in a liquid-fueled gas turbine combustor

Strict regulations on aviation gas turbine engine emissions and fuel consumption have driven the development of new lean burning, efficient gas turbine injectors. In an effort to increase fundamental understanding and support modeling efforts, great advancements have taken place in experimental measurement techniques. Specifically, in the field of laser diagnostics. This work describes the application of high repetition rate stereoscopic particle image velocimetry to a gas turbine combustor operating at representative engine conditions. The facility and test stand capabilities are presented along with the operational configuration for both the experimental and diagnostic systems. Finally, results are presented from two operating conditions, one with combustion and one without. Both 3-component SPIV and 2-component PIV data were collected simultaneously at 6 kHz. The vector fields generated from both techniques are compared both qualitatively and quantitatively.
