Abstract Data have been obtained for the three components of velocity and accompanying fluctuations in the near-injector region of a laboratory-scale research furnace. Flame stabilization was accomplished aerodynamically, with a swirl number of 1. Kerosene was used as fuel, excess air was supplied at 50%. The data show that the flow contains six distinct regions: the main air and fuel jets, internal and external recirculation zones, a high intensity combustion zone, and an intermittent recirculation zone in the nozzle wake region. Fluctuations in the three velocity components were found to be of approximately the same value, except immediately adjacent to mean velocity gradients. Inlet boundary conditions of the main air stream show a high degree of sensitivity to the entrainment ability of the fuel jet.
