I used a bipolar pulsed power(with a peak to peak voltage of 100kV,pulse repetition rate of 0~200Hz).Dicharge was carried out in a DBD configuration reactor with a wire to cylinder geometry electrode.Discharge electrode is metel rod while the grounded electrode is a reticulate stainless steel.Dicharge electrode was fully covered by a quartz glass tube.Air bubbles was artificially bubbled into the water.Gap distance varied between 5~50 mm. And what's more, when solid dielectric particles and the artificially created air bubble simutaneously present in water, the medium system become much more complex. How does the polarization electric field of the dielectric particles affect the discharge of the bubbles? I am not so familar with this field.I occasionally find these phenomena,and feel that they are so interesting.I am not sure whether i have made me known. thank you for your reply! Best regards!
thank you Bert!
I found that the increase of the conductivity of water decreased the breakdown of the air bubbles. can this be attributed to the decrease of k of water,thus induced the change of the electric distribution inside the gas bubble? Actually, i have no more idea about that!
