On the Performance of High Voltage Electrospray Echnique for Producing Nanoparticles

Electrospray technique is one of the commonly used methods for generating nanoparticles. In this method, the chemical solution which consists of a polymer and its solvent are injected into an electric field via a nozzle. At the end of this nozzle, due to electric forces, a certain part of this liquid is separated. Then, the separated part is divided into smaller particles and the solvent is evaporated and hence, the nanoparticles are acquired. Produced nanoparticales are collected in deionized water placed under the certain distant from nozzle. However, construction of this method is generally based on practical results. In this paper, modeling and performance evaluation of high voltage electrospray technique for producing the nanoparticles is presented. The proposed modeling algorithm uses numerical methods for calculating the electric field distribution. The proposed model can predict the effect of various parameters such as electric field characteristics on the generation process of nanoparticles. Simulation and Experimental results will be presented to show the validity of theoretical analysis.
