EGWIn Project Exploring ultra-low Global Warming potential gases for Insulation in high-voltage technology

Exploring ultra low global warming potential gases for insulation in high-voltage technology: Experiments and modelling” is a three year research project whose primary aim is to combine the experimental and theoretical work in order to determine the insulation characteristics of ultra low GWP gases and to consider the potential use of those gases for applications in high‐voltage power equipment. T

he long term goal of this project will be to develop the experimental infrastructure and theoretical basis for accurate measurements and advanced modelling of charged-particle transport properties with the aim of predicting the insulation characteristics of strongly electronegative gases.

📄 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.

🔳 The second workshop on Swarm Physics and Gaseous Dielectrics (2nd SPGD) was held on Monday, August 26th, during the SPIG2024 conference in Belgrade. Leading specialists from universities, research laboratories, and funding agencies worldwide gathered at the meeting, where they focused on swarm-based studies to advance and utilize gaseous dielectrics in high-voltage technology.

◽ The workshop is designed to examine experimental and theoretical methods for studying charged particle interactions with molecules, including scattering and transport, in both gaseous and condensed phases.

▪ The 2nd SPGD workshop was supported by the Science Fund of the Republic of Serbia, Grant No.7749560, project EGWIn.

📄Dr Sanja Tošić was one of the coauthors of the fifth EGWIn paper The radiative processes involving some non-symmetric systems relevant for astrochemistry: data needed for modeling.

The authors investigated the photo-association, charge-exchange, and photo-dissociation absorption processes in non-symmetric systems. They provided datasets that can be applied to important tasks, such as modeling laboratory plasmas and various astrophysical objects, or for use in the PLEIADES SOLEIL synchrotron.
