Abstract
The gamma function distribution is used to discuss droplet size variation for flat fan and round orifice atomizers. A technique of using multiple‐probe devices to measure droplet size, distribution and flux when the form of the distribution is known is described. Experimental results with a four‐unit conductance probe device are given for a Spraying Systems Tee‐jet operating with a slightly conducting liquid at 4.2 dm3/s and at an air velocity of 75.6 m/s. Probe results give a mass mean diameter of 68 μm while the standard photographie method gives 78 μm. A material balance using probe results gives a liquid flow of 6.0 dm3/s. The accuracy of this method is easily improved by adding more units, but the restrictions of conducting liquid and the mechanical problems of probe construction and calibration indicate that optical probes should be investigated.
