Propagation of a kerosene spray formed by a prefilming airblast atomizer within a pulsating flame has been investigated. The measurements were performed in a 400 kW single combustor rig at typical engine conditions of up to 0.8 MPa inlet pressure and 673 K inlet temperature. The homogeneity of the fuel spray propagation in the reacting zone substantially influences the local temperature distribution in the reaction zone and, therefore, the formation of thermal NO(chi). Phase locked visualization of the spray propagation and the flame luminescence was applied to the pulsating combustion process in order to analyze the complex interaction between the time dependent flow field, the spray propagation, and the combustion process. The spray characteristic was additionally investigated by means of time resolved PDPA measurements in the reacting flow.
