Simulation-driven Electrical Impedance Tomography for buoyancy-driven electrolyte mixing: A hybrid hydrodynamic–circuit modeling framework

This dataset accompanies the article “Simulation-driven Electrical Impedance Tomography for buoyancy-driven electrolyte mixing: A hybrid hydrodynamic–circuit modeling framework” (Measurement, 2025, https://doi.org/10.1016/j.measurement.2025.119745). The data represent a physics- and hardware-consistent, EIT benchmark case of single-phase, buoyancy-driven mixing of an electrolyte in a laboratory-scale vessel. Starting from numerical solutions of the coupled Stokes–Boussinesq and advection–diffusion equations, local solute concentrations are converted into conductivity fields and then mapped onto a multi-electrode EIT tank model implemented as a resistor network. The resulting files include time-resolved concentration and conductivity fields, axisymmetric conductivity maps, and simulated boundary voltage measurements generated with a circuit-level EIT front-end. Together, these materials allow readers to reproduce the forward simulations in the paper, to regenerate key figures, and to use exactly the same ground-truth fields and measurement data for benchmarking alternative EIT reconstruction algorithms and evaluation metrics described in the publication.
