In this paper from collaborative research of the Institute of Chemical Reaction Engineering and the Institute for Mechatronics in Mechanics at the Hamburg University of Technology, a modular, end-to-end simulation benchmark for EIT in chemical reactor monitoring is presented. The goal is to enable controlled and repeatable evaluation of EIT reconstruction methods in a realistic, physics-based setting. The framework integrates the full pipeline — from hydrodynamic transport and electrochemical modeling to hardware emulation and image reconstruction.
The highlights of the publication are:
- Simulative demonstration of End-to-End EIT for monitoring electrolyte transport.
- Modular framework: Each component — CFD solver, conductivity model, circuit generator, and EIT reconstructor — can be swapped independently for rapid prototyping.
- Circuit-level emulation: Conductivity maps are converted to equivalent resistor networks and simulated in LTspice alongside a 32-electrode measurement hardware.
