Numerical study of electrohydrodynamic atomization considering liquid wetting and corona discharge effects

In this paper, the behavior of cone-jet mode fluid by electrohydrodynamic atomization (electrospray) is numerically simulated and investigated with effect liquid wetting corona discharge effects. The simulation was performed contact angle condition to fit Taylor cone shape experiments. Experimental data are provided verify validate numerical method, followed additional analyses on effects electrical conductivity, surface tension, flow rate, viscosity electrospray characteristics, including spray current jet diameter. Numerical results simulations in reasonable agreement experiments consistent literature. Analyses different angles suggest potentially major impacts factor high voltage low rate circumstances. Furthermore, influence also both electrospray–corona experiment using a high-speed camera, yielding significant improvement prediction for formation. indicate that capillary nozzles would be vital formation studies.
