Positive and Negative Pulsed Corona in Argon
Photographs are obtained of corona discharges in argon at atmospheric pressure using a high resolution, intensified CCD camera. Positive and negative polarity is applied at the curved electrode in a point-plane gap and a plane-plane gap with a protruding point. Branching is observed in the positive point-plane gap but it is much less pronounced than in air probably due to the much lower energy ...
متن کاملIonization fronts in negative corona discharges.
We use a hydrodynamic minimal streamer model to study negative corona discharge. By reformulating the model in terms of a quantity called a shielding factor, we deduce laws for the evolution in time of both the radius and intensity of the ionization fronts. We also compute the evolution of the front thickness under the conditions for which it diffuses due to the geometry of the problem and show...
متن کاملThe relationship between positive and negative affect and psychosocial function in the corona epidemic: the mediating role of psychological resilience
The aim of this study was to investigate the mediating role of psychological resilience in the relationship between positive and negative emotions and the psychosocial functioning of individuals during the corona. The design of the present study was descriptive correlation and path analysis was applied. The statistical population included Iranian adults, of which 461 people participated in this...
متن کاملModel Calculation of Negative Wire-Cylinder Corona Discharge Properties in Humid Synthe- sis Gas
For the final clean-up of the synthesis gas produced from a small scale biomass gasification plant having a gas flow rate of 35 kg/hr a wet ESP has been designed and tested. Design was supported by model calculations of the current-voltage characteristics of the wire-tube precipitator. Electronic and ionic properties of multi-component gas mixtures were evaluated from cross section data using a...
متن کاملCorona of Magnetars
We develop a theoretical model that explains the formation of hot coronae around strongly magnetized neutron stars — magnetars. The starquakes of a magnetar shear its external magnetic field, which becomes non-potential and is threaded by an electric current. Once twisted, the magnetosphere cannot untwist immediately because of its self-induction. The self-induction electric field lifts particl...
