Abstract
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.
