Experimental study on electrohydrodynamic atomization of aqueous salt solutions

Effects of electrical conductivity on spraying modes and behavior of produced drops and microdrops have been studied experimentally. A metallic nozzle with 0.6 mm ID as high voltage electrode and a stainless steel ring as a ground electrode were employed. Four different aqueous KCl solutions were sprayed in various high voltages and flow rates. Results confirm that spraying modes changes with conductivity variation. The sizeand velocity of emanated droplets were also investigated in order to present a deep insight to the electrospraying phenomenon.
