Characterization of Spray-Drying Nozzles at Industrially Relevant Conditions

This project sought to develop physically realistic models for atomization processes relevant to particle production, such as in spray-drying processes, with a focus on high viscosity and non-Newtonian fluid atomization. The goals of this work were to generate a spray database and to develop understanding and correlations for the accurate pilot-to-production scaleups. We divided the work to focus on two nozzle types: pressure-swirl, and two-fluid nozzles.
