Time-resolved PIV measurements applied to a non-reactive dodecane-air mixture in a two-staged multi-injection burner

Résumé

Lean premixed prevaporized burners seem good candidates to reduce pollutant emissions from gas turbines. Indeed, lean combustion regimes result in lower temperatures and therefore a reduction on the NOx emissions, major pollutant species. However, these burners are very sensitive to combustion instabilities (flashback, flame extinction or pressure oscillations). To face this problem, multi-injection staged combustion is envisaged first to keep the good fuel-air mixture and second to control the fuel distribution. To fully understand the flame's behavior while using a two-phase flow, it is necessary to characterize the nonreactive flow at the same operating conditions in order to detect any instability. Time-resolved Particle Image Velocimetry will be used to characterize the droplet dynamics and the effect of fuel distribution on the resulting spray.
