SUMMARY

The discussion centers on the temperature of air during a corona discharge and its classification as an adiabatic process. It is established that corona discharge occurs when the electric potential reaches approximately 30 kV per meter, leading to ionization of air. However, the exact temperature attained during this phenomenon is not definitively stated, and the mechanism of charge separation remains unclear. Participants express uncertainty regarding the adiabatic nature of the process, indicating a need for further exploration of these concepts.

PREREQUISITES
  • Understanding of corona discharge phenomena
  • Knowledge of electric potential and ionization
  • Familiarity with thermodynamic processes, particularly adiabatic processes
  • Basic principles of atmospheric physics
NEXT STEPS
  • Research the temperature profiles associated with corona discharge events
  • Explore the principles of adiabatic processes in thermodynamics
  • Investigate the mechanisms of charge separation in electrical discharges
  • Study the effects of electric fields on air ionization
USEFUL FOR

Physicists, electrical engineers, and anyone interested in atmospheric electricity and the behavior of gases under high electric fields.

We're not sure. We know that areas having a high electric potential as compared to the ground evolve under the right conditions. Eventually the potential is high enough for a discharge to occur [I think about 30KV per meter], but the mechanism of charge separaton is not understood - at least there is no explanation that is universally accepted as being definitive.
 


Okay, My question is related to this topic so I will ask it here rather than creating a new topic.

I want to know the temperature attained by the air around a
space(at normal temperature and pressure) where a corona discharge takes place.
Also can the process of corona discharge be taken as an adiabatic process?

Thanks in advance for the replies.
