Study of the Atomization Fragmentation Mechanism Under the Electrostatic Field

In the process of liquid electrostatic atomization, the electrodynamic force will play an important role in the development of surface fluctuations, which is the problem of instability of surface fluctuations of liquid jets. This paper analyses the linear stability of non-Newtonian jets (viscoelastic planar liquid film and cylindrical jets) and Newtonian jets (viscous cylindrical jets) with small surface perturbations in the radial electric field, deduces the dispersion equations, and accordingly discusses the influence of dimensionless parameters such as the electric Euler number, the Weber number, and the Reynolds number on the stability of these jets. The atomization mechanism of the viscous cylindrical jet is initially studied by analyzing the linear stability of the viscous jet in the radial electric field, which provides a certain theoretical basis for the extinguishing of the charged fine water mist.
