equations (NeS equation) can be applied in this case. A wall boundary condition has been implemented on both electrodes, i.e., a pressure of 1.01105 Pa on the outlet and a normal velocityfield in the inlet. The operating gas was ambient air (densitywas 1.19 kg/m3 , viscosity was 1.79 105 kg/m/s, and the relative permittivity constant was 1.00054). The PTFE insulator permittivity constant was 2.1.
