Abstract :
Streamers appear in gases, liquids, and solids due to impact ionization in high electric fields near streamer tips. Dynamically adaptive mesh enables high resolution of sharp streamer fronts with a large dynamic range and a minimum number of computational cells. We present results of computational experiments utilizing dynamically adaptive Cartesian mesh for multiscale resolution of streamers near curved electrodes in 2-D and 3-D geometries.
