Figure 4.
The panel a shows electric potential contours at 0.75, 1, 1.25, and 1.5 kilovolts, with x from negative 200 to 500 micrometres and electric potential from 0 to 1.5 kilovolts. Graph b shows jet diameter decreasing from about 7.2 micrometres at 0.75 kilovolts to about 4.8 micrometres at 1.5 kilovolts. Graph c shows jet length increasing from about 70 micrometres at 0.75 kilovolts to about 190 micrometres at 1.5 kilovolts.Baseline tests for ES with varying applied voltage from 0.75 to 1.5 kV and a steady liquid flow rate of 0.75 m/lh
Note(s): The figure shows (a) the electric potential field, (b) jet diameter and (c) jet length with standard deviation in grey colour
