Positive streamer discharge simulations in humid air: uncertainty in input data and sensitivity analysis Open

Baohong Guo, Hemaditya Malla, Alejandro Malagón‐Romero, Jannis Teunissen · 2024

We study how the choice of input data affects simulations of positive streamers in humid air, focusing on H2O cross sections, photoionization models, and chemistry sets. Simulations are performed in air with a mole fraction of 0%, 3% or 10…

Calculating radio emissions of positive streamer phenomena using 3D simulations Open

Hemaditya Malla, B. M. Hare, Steven Cummer, Yihao Guo, Alejandro Malagón‐Romero , et al. · 2024

We study radio emissions from positive streamers in air using 3D simulations, from which the radiated electric field is computed by solving Jefimenko's equations. The simulations are performed at 0.5 bar using two photoionization methods: …
