This dataset was created by researchers from the Centrum Wiskunde & Informatica (CWI, the Netherlands) and the Instituto de Astrofísica de Andalucía (IAA, Spain). It contains 1000 axisymmetric positive streamer discharge simulations. The dataset is generated by varying the applied voltage and electrode geometry, with all simulations conducted in air at 1 bar and 300 K. The core content of this dataset includes fitted expressions for the streamer radius, velocity, and linear conductivity, which are derived based on the length scale of the high-field region near the streamer head. The process of creating this dataset involved numerical simulations using a fluid model, with adaptive mesh refinement (AMR) techniques adopted to enhance computational efficiency. The primary application domains of this dataset focus on the simulation and prediction of electrical discharge phenomena, aiming to construct simplified data-driven models to address the issue of high computational costs in traditional simulation methods.
