SINOPSIS

Many studies on twin-fluid sprayers have presented results for systems in which the liquid was force-fed. The present study involved using an air-atomizing two-fluid sprayer, without liquid force-feed, to produce free sprays. The drop size data from the free sprays were obtained using a laser-diffraction-based drop size analyzer. The spray drop size was measured at various air atomizing pressure levels, axial distances from the injection nozzle, and radial distances from the spray centerline. These were used to characterize the hydrodynamics structure of the sprays. Test results indicate that, even more than in liquid force-fed systems, the performance of the air atomizer depends largely on the air atomizing pressure. This restricts the liquid atomizing range and leads to poor spray atomization at low air pressure values. At higher air pressure values, the drop size distribution was observed to be bimodal, thus presenting another challenge for computational studies. However, because they do not require liquid pressure systems, they may be simpler/cheaper to operate compared to force-fed systems.
