The electrostatic charged spray could reduce the viscosity resistance and enhance the atomization effect. After the droplets come into being, the electric field can minish the droplets surface tension and make the droplets produce the second atomization, and further the droplets become much smaller and the uniformity of droplets diameter is improved. With the air and water as working fluids, the experimental research of twin-fluid charged spray nozzle designed by oneself was studied. The droplets diameter, the axial jet velocity and turbulent fluctuation intensity under the different charged voltages and gas-liquid ratio were obtained. The measure of two phases flow velocity and turbulent fluctuation intensity were determined. The influence of charged voltage and droplets diameter, axial jet velocity, turbulent fluctuation intensity were discussed. 
