Experimental Research of M5 Nozzle Droplet Particle Size Distribution
Nozzles are widely used in many fields as important devices for liquid atomization.In light of the droplet particle size distribution (PSD) characteristics of M5 nozzle used in low-temperature multi-effect water desalination technology,this paper specifically designed special measurement system,and condected the PSD experiment of single nozzle in normal temperature and pressure conditions.As the experimental results show,under the same flow rate,on the cone cross section formed by spray droplets,the U-shape droplet diameter is distributed ; with the increase of flow rate,droplet diameter becomes shorter,droplet diameter distribution more uniform,and nozzle spray angle larger at the same time ; during droplet size measurement,the flow is more volatile when the covering water plate spacing is 2 cm than the spacing is 4 cm.
