TL;DR
This paper investigates the transition from avalanche to streamer in particle simulations, highlighting similarities to fluid models and emphasizing the importance of hybrid models due to numerical artefacts introduced by super-particles.
Contribution
It demonstrates the avalanche to streamer transition in particle models and discusses the impact of super-particles, advocating for hybrid modeling approaches.
Findings
Results align with fluid model behaviors.
Super-particles cause numerical artefacts.
Hybrid models are necessary for accurate simulations.
Abstract
The avalanche to streamer transition is studied and illustrated in a particle model. The results are similar to those of fluid models. However, when super-particles are introduced, numerical artefacts become visible. This underscores the need of models that are hybrid in space.
