The drop size distribution (DSD) and the spray angle of full cone nozzles are measured at different atomization pressures and corresponding volumetric flow rates of water. The measurements of the DSDs were performed with laser diffraction spectrometry. The nozzles characterized here are geometrically similar models in the photo scale 1:8, 1:10, and 1:12 in relation to the original nozzle (1:1) used as the main sprayer in an industrial dust scrubber with an orifice diameter of D(N) = 96 mm. For all nozzles the spray pattern and flux density is characterized by means of a mechanical patternator. The overall volume frequency distribution q(3)(d) is calculated by a weighting procedure. The dimensionless droplet diameter d(p)/D(N) for different characteristic drop sizes (d(10.3), d(50.3), and d(90.3)) can be extrapolated to the operating conditions of the original nozzle. The spray angle of the full cone nozzles is obtained by evaluation of photographical spray images. It is found to depend on the Reynolds and the Ohnesorge number.
