cone-jet mode in electrostatic field

Hi,

Here is my problem.
I want to simulate a electrohydrodynamic (EHD) phenomenone , a nozzle with full water (or electrolyte) in a electrostatic field, the the water is polarized and deformed the Taylor cone,then comes the cone-jet mode. My models include the level set -laminar flow and electrostatic,but still cann't get the cone-jet result.Is there anybody also working on a similar model like mine?Did you get the cone-jet results?

Thank you.
