Experimental Research on Electrostatic Spray of Liquid Fuel

Spray combustion is the basic combustion pattern of liquid fuel and the quality of atomization is the key to improving combustion efficiency and decreasing emissions.A new kind of combustion technology-electrostatic spray combustion is developed by applying electrostatic spray to fuel combustion. In this paper, a charging device of liquid fuel is developed. The electrostatic spraying characteristics of fuel are experimentally investigated for the first time by PIV. The droplet size and the charge to mass ratio are measured by developing a device of particle charge to mass ratio and the reagent of catching fuel droplets. The experimental results show that the droplet diameter of electrostatic spray decreases by 50 percent.
