Method and system for treating fluids by producing corona discharges in a fluid volume

The invention relates to a method for treating fluids (5) by producing corona discharges (12) in the fluid volume (6). According to said method, high-voltage pulses (8) are applied to an electrode arrangement (2) present in the fluid volume (6). Pulse rise times of the high-voltage pulses (8) are in the range of 1 to 40 nanoseconds and pulse duration of the high-voltage pulses (8) is in the range of 50 to 400 nanoseconds.

Influence of surface parameters on dielectric-barrier discharges in argon at subatmospheric pressure - dataset

The provided data describe the discharge current in DBD obtained by fluid modelling using different values of for the secondary electron emission coefficient γ and and the relative permittivity of the dielectric barrier εr in comparison with the measured current at a pressure of 100 mbar and an applied voltage amplitude of 1.8 kV. Furthermore, the dissipated power obtained by model calculations for different values of γ and εr together with the measured power in dependence on the pressure is given.
