3D Streamer Simulations: Branching, Radio Emissions, Air Density Shocks, and Magnetic Fields
ONLINE POSTER SESSION FOR ATMOSPHERIC AND SPACE ELECTRICITY I
atmospheric and space electricity | 22 january 2024
Ute Ebert, Jannis Teunissen, Baohong Guo, Dennis B...
3D streamer models are required for many discharge phenomena, as soon as the axisymmetry of a single streamer is broken. I will review recent progress...
