Using the Advanced Photon Source at Argonne National Laboratory, high-resolution focused beam X-ray measurements are acquired and used in studying break-up mechanisms in the near-field region of an airblast atomizer. The nozzle used in the experiments is a two-fluid coaxial airblast atomizer with inner liquid flow rates that are within the laminar regime and outer air flow rates in the turbulent regime. This study works to determine the effect of electrifying the liquid portion of the spray. The average mass distribution and standard deviation are two of the measures used to examine the extent to which the flow direction and break-up can be manipulated. Electrifying the nozzle is explored as a method of real-time control of the spray field.
