🔥 Graphite Furnace Cross-Section: Joule Heating, Radiation-Augmented Insulation and Graphitization Kinetics (2D)

2D companion of the synthetic graphite furnace: radial heat conduction in a Joule-heated coke core inside insulating packing, temperature-dependent resistivity and conductivity, Arrhenius graphitization degree, energy use, and five in-page numerical checks.
