Present work is devoted to experimental study of reacting jet flow in a model open flame burner. The work was inspired
by the problem of extension of the range for stable and effective combustion which basically determined by the turbulent
flow structure in reaction zone. To approach this target spatial distributions of the mean velocity, turbulent kinetic energy
were measured and the role of organized vortical structures have been studied.The main technique used is a laser based
stereo Particle Image Velocimetry (PIV) system. The measurements were performed in a central section of the jet
flame. Regular swirl parameter of the flow was varied from 0 to 1.0. Reynolds number was changed between 1000 and
8000. Equivalence ratio variation band was between 0.5 and 4. Effect of the nozzle geometry was studied by using
nozzles with different exit diameters.
