This paper was focused on studying of turbulent mixing in a model gas-turbine combustor by using planar laser-induced fluorescence. The case of model fuel injection through the pilot jet with Re = 30 000 was considered. Acetone was used as a fluorescent tracer. Data processing methods including correction of sensor sensitivity, background signal correction and correction of non-uniformity of the laser sheet were described. The instantaneous and averaged concentration fields and the concentration pulsations were demonstrated.
