Discharge growth simulation between parallel-plate electrodes using various computation techniques

Abstract EN

In this work, a simulation of the discharge growth between parallelplate electrodes is built up based on various computation techniques.

The continuity equations of different particle species existing in the discharge are solved by the characteristic method.

The electric field is evaluated by a disc method and one dimensional Poisson’s equation.

Excited atoms or molecules and photons due to photoionization process is also included.

The secondary electrons due to u.v.

light, positive ion and delayed and / or undelayed photon cathode bombardment are evaluated.

In this respect various computation techniques led to select the most accurate method used in the discharge simulation which enables the discharge to be traced to later stages.

The total gap current and breakdown time are discussed.

N2 gas is implemented in gap to study the discharge growth using various computation techniques.
