Zinc-Bromine Flow Battery: 2D Diffusion & Crossover Model

This is the 2D counterpart to the 3D zinc-bromine flow-battery simulator, and it deliberately implements the electrochemistry differently rather than just re-drawing the same tanks flat. Faraday's law still integrates current into zinc plating and Nernst's equation still sets the open-circuit voltage, but the bromine self-discharge pathway — normally hidden inside a single fitted decay coefficient — is here a genuine discrete-particle Monte-Carlo diffusion simulation: bromine tracer particles random-walk toward the membrane-free separator, and each crossing attempt is resolved live against the complexing-agent capture probability. Scrolling strip charts of state of charge and cell voltage, plus a live Nernst curve, sit alongside the cross-section so you can watch the microscopic crossing statistics drive the macroscopic battery readouts in real time.
