Implication

Computational modeling shows strong agreement between simulated and measured electric field profiles across air gap geometries, highlighting the accuracy of the Deutsch approximation.

Key Points

To assess the validity and accuracy of corona discharge simulations based on Popkov and Sarma models using the Deutsch approximation of electric field direction invariance.
Implemented Popkov and Sarma computational models incorporating the Deutsch approximation of invariant electric field direction.
Simulated current density and electric field profiles at collector electrodes for positive corona in wire-plane, paraxial-cylinder, and point-plane air gaps.
Benchmarked simulation outputs directly against experimental measurement data.
Simulated current density and field profiles demonstrated satisfactory qualitative and quantitative agreement with experimental measurements across all tested electrode configurations.
Theoretical analysis identified the electrostatic conditions explaining why the Deutsch approximation maintains low error margins despite simplifying assumptions.
