| Research Abstract |
This study proposes an analysis method of negative ion by electrostatic atomization. Because theelectrostatic atomization includes large deformation of a drop of water, it is difficult to analyze withconventional fluid analysis methods such as the finite differences method (FDM), the finite elementmethod (FEM) and so on. In this method, electrostatic field equation is coupled with Navier-Stokesequation of a drop of water, employing the moving particle semi-implicit (MPS) method and FEM. Thevalidity of the method is verified through the measurement. Comparing the calculated results with the measured results, the effectiveness of this method was confirmed.
