Characterization of the reactive flow field dynamics in a gas turbine injector using high frequency PIV

Understand

The present work details the analysis of the aerodynamics of an experimental swirl stabilized burner representative of gas turbine combustors.

• This analysis is carried out using High Frequency PIV (HFPIV) measurements in a reactive situation.
• While this information is usually available at a rather low rate, temporally resolved PIV measurements are necessary to better understand highly turbulent swirled flows, which are unsteady by nature.
• Thanks to recent technical improvements, a PIV system working at 12 kHz has been developed to study this experimental combustor flow field.
