Data and code for Mixing and capture limits in copper nanoparticle production by electrical wire explosion

This release contains data, computational models and code supporting the manuscript Mixing and capture limits in copper nanoparticle production by electrical wire explosion, by Wenli Zhu, Jiann-Wen Woody Ju and Liang Zhu. The archive includes copper-wire experimental summary tables, figure data and experimental image assets, analytical checks, MATLAB population-balance and transport calculations, COMSOL model files, solver outputs and numerical verification records. The calculations examine axial heat transport, Brownian coagulation, internal transport, partially absorbing collection, source placement and pulsed production. Data provenance, run order, software requirements and the relation between files and manuscript figures are documented in the archive. MATLAB R2026a and COMSOL Multiphysics 6.4 are external software requirements for the corresponding model reruns; proprietary solver software is not distributed. Numerical model scenarios are identified separately from experimental observations. This is a research-data release associated with a manuscript prepared for journal submission.
