Abstract
Using planar optical methods based on laser-induced fluorescence and
particle image velocimetry instantaneous velocity fields and passive tracer
concentration are measured simultaneously in a model of GT-combustor at
realistic flow rates. Spatial distributions of velocity pulsations and passive
tracer concentration pulsations are measured at air flow rate about 0.4 kg/s.
Correlations of velocity and concentration pulsations are measured. The most
intense turbulent mass flux in the region of swirling flow mixing layer was
observed. The contribution of advective and turbulent components in the
transfer of a passive tracer in the axial direction was estimated.
