The distribution of liquid discharged from spray nozzles is of critical
importance in many industrial applications. Many applications require arrays
of nozzles in order to effectively cover large areas. Optimization of
atomizer arrays depends upon accurate and comprehensive spray flux density
measurements of both the individual atomizer and of a cell of the array. Precise measurement of spray
distribution is also necessary to determine appropriate sampling protocols
for drop size and velocity measurements.
At spray research, flux density
distributions are performed using one of several tube patternators, our
proprietary scanning rate-of-change patternator or by normalizing the
pdpa data for the diameter- and trajectory-dependent sample volume and
particle transit time.
