Method of synthesizing sprinkler spray patterns. Research report
There are practical difficulties in obtaining data on water-sprinkler spray patterns over coal stockpiles under various wind conditions. A method is developed for synthesizing the spray-droplet patterns, based on laboratory tests to observe the droplets discharged from a sprinkler nozzle; this data is employed with the theoretical equations for droplet movement to calculate the trajectories of representative spray droplets, including cases where local air flows due to wind are important. From observations made by Watkins in the course of wind tunnel model studies of wind effects over coal stockpile areas, it was evident that local air flows could have a marked effect on the trajectories of water droplets from water sprinklers used for dust suppression.
