Resumen
Purpose – The purpose of this paper is to propose an analysis method of negative ion by electrostatic atomization. Because the electrostatic atomization includes large deformation of a drop of water, it is difficult to analyze with conventional fluid analysis methods such as the finite differences method, the finite element method (FEM) and so on.
Design/methodology/approach – In this method, electrostatic field equation is coupled with Navier‐Stokes equation of a drop of water, employing the moving particle semi‐implicit method and FEM. The validity of the method is verified through the measurement.
Findings – It was found that the difference between calculated and measured results becomes large as the voltage increases.
Research limitations/implications – In order to improve the accuracy, it is necessary to improve the way to calculate surface tension and the analysis condition.
Originality/value – This paper confirms the usefulness of the numerical method to elucidate electrostatic atomization.
