Abstract [en]

A continuous current with a potential ranging between 10 and 30 kV was applied to a single-hole nozzle for modifying the properties of the generated water spray. The nozzle produced a full-cone spray by injecting water into quiescent air at atmospheric conditions varying the injection pressure between 0.2 and 0.6 MPa. Back-illuminated photography and laser-based holography were used for recording the effect of the electrical current on spray properties such as cone angle and droplet sizes. Results from this study indicate that applying a potential above 20 kV yields wider cone angles, more homogenously distributed spray patterns, and reduced droplet sizes than non-assisted sprays.Key words: electrosprays, water mist
