| Abstract: | Our objective is to analyze the atomization processes of a pneumatic atomizer by measuring the size and velocity distributions of droplets in a liquid paint spray. The droplet size and velocity distributions have been determined at different axial positions in the spray; a mathematical description of how these quantities vary throughout the spray is then proposed. Additionally, the relative number density of droplets and the relative local mass flux are estimated. |
