The drop-size distribution of Bingham liquid sprays was determined by experimentation. Three different highly viscous paints were sprayed with fan-jet airless spray nozzles at pressure ranging from 5 170 to 18 200 kPa. A collection device was constructed to capture a spray sample on microscope slides. Measurement of flattened droplet diameters with a microscope yielded drop-size distribution curves of accumulated volume per cent versus volume median diameter. It was postulated that the wall shear stress existing at the exit plane of the nozzle initiated liquid atomization. A logarithmic correlation was found between shear stress and volume median diameter.
