Figure 5.
The panel a shows velocity contours for F F, E F F, and E S, with x from negative 200 to 500 micrometres and velocity from 0 to 100 metres per second. Graph b shows jet diameter decreasing from about 7.8 micrometres at F F to about 5.6 micrometres at E F F, then increasing to about 7.2 micrometres at E S. Graph c shows jet length decreasing from about 235 micrometres at F F to about 95 micrometres at E F F and about 65 micrometres at E S.Comparison between FF, EFF and ES with a liquid flow rate of 0.75 ml/h (all cases) and gas pressure of 4 kPa (FF, EFF) and electric potential of 0.75 kV (EFF, ES)
Note(s): The figure shows (a) the gas velocity field, (b) jet diameter and (c) jet length with standard deviation in grey colour
