【Abstract】 Spatial distribution of spraying drops size and concentration are important parameters to investigate spraying field. In this paper, the spray characteristics of LNN14 nozzle are measured by spray optical system. The distribution of droplet diameter and concentration are obtained in different pressure condition and spray distance, and the variation rule of the spray particle size and density is obtained with pressure and spray distance. It also provides a basis gist for decreasing the smoke plume temperature of the warship.更多还原
