📄 NEW PAPER 📢
Axisymmetric fluid streamer model in the AMReX library
🖨 Published on 29 August

The authors discuss implementing an axisymmetric fluid model of streamers, based on the first-order fluid model, in the AMReX open-source library. They verified the code under standard conditions by comparing results for positive streamers in the air with existing literature benchmarks. Additionally, they verified the code’s performance in strongly attaching gases by comparing results for negative streamers in CO2 and C4F7N mixtures with those obtained from the Afivo-streamer code.

📢 Dr Zoran Raspopović is author of the third EGWIn paper: Space-resolved average kinetic energy of ion swarms in a uniform electric field.

ℹ Dr. Zoran Raspopović discusses new aspects of spatial relaxation of charged-particle swarms in a uniform electric field. Special attention is paid to:

1. determining whether the average swarm kinetic energy at the leading edge reaches some constant stationary value or decreases during swarm evolution, and
2. identifying the spatial locations where drifting charged particles gain and where they lose energy during swarm evolution.
