Optimization of an Annular Jet Commercial Gas-Metal Atomizer



Stephen D. Ridder, Aaron N. Johnson, Pedro I. Espina, Frank S. Biancaniello, G J. DelCorso


The performance of a commercial gas-metal atomizer was studied using a number of previously published research techniques. initially the flow was visualized using schlieren photography to determine the location of important flow features (e.g., shock waves, expansion fans, shear layers). With this information at hand, an experiment was designed to determine the aspiration performance of two prototype geometries. The aspiration results were confirmed with the help of computational fluid dynamic models, which although not as accurate, yielded more spatial resolution of the phenomena present. Using these results, a number of 316 SS production runs were performed, and it was concluded that the recommendations suggested by the fluid experiments produced improvements in the fine powder yield of the considered geometries.
