Figure 13.
The graph plots volumetric charge density in per cubic centimetre against radial distance from the interface in micrometres. The jet region occupies the shaded area from negative 2 to 0 micrometres. An arrow at the interface points toward the jet region and marks alpha as 0.5. Three curves represent K values of 4.6 times 10 negative 6, 1.6 times 10 negative 6, and 5.7 times 10 negative 7 siemens per metre. All curves peak near 0 micrometres. The curve for K at 4.6 times 10 negative 6 siemens per metre reaches about 103 per cubic centimetre. The curve for K at 1.6 times 10 negative 6 siemens per metre reaches about 71 per cubic centimetre. The curve for K at 5.7 times 10 negative 7 siemens per metre reaches about 43 per cubic centimetre. The curves decrease on both sides of the peak and approach 0 beyond about 2 micrometres.Volumetric charge density distribution along the radial direction at the orifice exit ()
Note(s): The plot is zeroed at the interface at (the grey area marks the jet). All cases have a pressure of 2 kPa, a liquid flow rate of 0.75 ml/h and an electric potential of 0.75 kV
