Figure 12.
The panel a shows electric field magnitude contours at 1.62 times 10 negative 6, 4.6 times 10 negative 6, and 5.2 times 10 negative 5 siemens per metre, with x from negative 300 to 300 micrometres and electric field magnitude from 0 to 10 megavolts per metre. Graph b shows jet diameter decreasing from about 6.7 micrometres to about 4.7 micrometres as electric conductivity increases. Graph c shows jet length increasing from about 65 micrometres to about 94 micrometres, then decreasing to about 82 micrometres as electric conductivity increases.Electric conductivity influence on the EFF jet diameter and length at a gas pressure of 2 kPa, a liquid flow rate of 0.75 ml/h and an electric potential of 0.75 kV
Note(s): The figure shows (a) the gas velocity field with streamlines inside the capillary needle, (b) jet diameter and (c) jet length with standard deviation in grey colour
