The work is concerned with the modeling of low-current quasi-stationary discharges, including Townsend and corona discharges. aim to develop an integrated approach suitable for computation whole range existence a discharge from its inception non-stationary transition another form, such as normal glow or corona-to-streamer transition. This task includes three steps: (i) ignition self-sustaining ...

In the previous paper, a novel fine particle removal system composed of a corona-discharge neutralizer, a pulse-jet air unit and an image processing system has been developed and applied to the removal of fine particles from film surface. We have calculated the van der Waals and electrostatic forces between particle and film and then reported that the electrostatic force influenced the adhesion...

Abstract When corona discharge occurs around the wire, it will be accompanied by movement of space charge, and then generate effects such as radio interference audible noise. In order to reveal time domain characteristics electric field generated discharge, a set measurement systems for interference, including oscillator antenna, sampling resistance, data acquisition system, is developed. Based...

The technique used to control the airflow is based on the electro-hydrodynamic actuator which is also called plasma actuator. This actuator ensures the airflow control thanks to the electric wind created by the electrical corona discharge. This ionic wind is developed at the profile surface tangential to the initial free airflow so that it has a significant effect on the boundary layer flow. Th...

In power systems, corona discharge often occurs, which is a common phenomenon. If it occurs in electrical equipment, then hidden dangersexist, such as poor contact between metal fittings of insulators and insulation performance degradation due to equipment agingand strand breakage transmission lines. These dangers may lead further serious accidents. So, very important detect eliminate the dange...
