Abstract

Fine Coulomb fission of liquid droplets charged to the Rayleigh limit is modeled, combining the theories for the flow-limited field-injection electrostatic spraying and the conventional electrostatic spraying. The model gives expressions for the current, flow rate, jet growth rate, and secondary droplet size in the fine Coulomb fission process. The model can explain the reported experimental results and completes the previous model on Coulomb fission.
