Experimental study on the gas-liquid two phase flow of air-assist boom spraying

摘要：

　　The velocity and diameter distribution of the air-assist boom spraying is studied by a laser Phase Doppler Particle Analyzer when the operational parameters is changed,which including airflow velocity of air curtain and vertical relative position between the air curtain and the nozzle.Frorn the experimental results,we find the as the air curtain velocity increases,the size distribution of the droplet is conducive to uniform.At the same air curtain velocity,droplet size decreases with increasing of nozzle pressure.On the right side of each measuring point,the number of droplets is gradual decreasing with the wind velocity increasing.When the working pressure is 0.5Mpa,the droplet size does not change with the change of the horizontal distance.
