The paper presents the effect in removing organic compounds from water that the Surface gliding discharges (SGD) has it. A SGD is an electrical discharge, formed between two divergent electrodes thin type, “wire type”, generated in a flow of gas, with a high flow rate. The non-thermal plasma, in contact with the solution film formed on the walls of reactor, leads to the organic compound disolved in...
Discharge plasma generated by pulsed high voltage applied to water is used in industry for such purposes as improving water quality. High voltages have been considered necessary for discharge plasma in water. However, discharge plasma in water was here generated using a low applied voltage of 3 kV by capacitor discharge circuit. This report discusses two experimental methods: one using an MPC (Magnetic...
The goal of this paper is to investigate and model the effect of non uniform discontinuous pollution on flashover of laboratory plate insulator. The experimental results show that the discharges appear almost simultaneously at the point and the dry bands whatever the polarity of the applied voltage. The lengths of discharges as well as the critical flashover voltage depend on the configuration of...
Electrothermal plasma sources have numerous applications including hypervelocity launchers, fusion reactor pellet injection, and space propulsion systems. The time evolution of important plasma parameters at the source exit is important in determining the suitability of the source for different applications.
Three groups of different initial NO concentration experiments were conducted using a concentric cylinder double dielectric-barrier discharge reactor to investigate how variational initial NO concentrations affect the effectiveness of dielectric barrier discharge (DBD) treatment flue gas pollutants. Results show that the input energy density increases with increasing the initial NO concentration under...
An electrical discharge in a bubble in water and above the water surface were applied to generate active radicals such as atomic oxygen, ozone and hydroxyl for wasted water treatment. The discharge along the inside of the bubble was optically observed. The onset voltage for different gases was measured with the different water conductivity. The use of discharge above the water surface was proposed...
It is necessary for electrical insulation diagnosis to obtain information about the electric field distribution and the space charge distribution in insulation materials. We have investigated the measurement of nonuniform electric field vector distributions in liquid dielectrics using an original method based on electrooptic Kerr effect and CT method. We carried out the time series measurement of...
