Positive Streamer (IMAGE) American Institute of Physics Caption This is a typical view of positive streamer branching in a liquid dielectric, (top) experimental images of a positive streamer initiated from a needle electrode and, (bottom): 3-D modeling result of a corresponding case (iso-surface plot of the electric field distribution). The streamer structures are qualitatively similar in experiments and simulations. The fractal structure of the streamer tree in the experimental image makes it possible to compare the modeling result a lso with other nodes of the tree including the one at the needle electrode tip.
