A comparison of the flowfields and emissions of high-swirl injectors and low-swirl injectors for lean premixed gas turbines

Abstract A new approach for low emission gas turbines was investigated by modifying a typical production high-swirl injector (HSI) for gas turbine combustors to operate in a novel low-swirl mode (LSI). This LSI (S = 0.5) was configured in the laboratory and investigated by particle image velocimetry at firing rates of 9–87 kW (1
