Fire-X: Extinguishing Fire with Stoichiometric Heat Release
DescriptionWe present a combustion simulation framework to model fire phenomena across solids, liquids, and gases. Our approach extends traditional fluid solvers by incorporating multi-species thermodynamics and reactive transport for fuel, oxygen, nitrogen, carbon dioxide, water vapor, and residuals. Combustion reactions are governed by stoichiometry-dependent heat release, allowing accurate simulation of premixed and diffusive flames with varying severity and composition. We support a wide range of scenarios including jet fires, water suppression (sprinklers, sprays), fuel evaporation, and starvation conditions. The system enables interactive heat sources, fire detectors, and realistic rendering of flames (e.g., laminar-to-turbulent transitions, blue-to-orange color shifts). Our key contributions include the tight coupling of species dynamics with thermodynamic feedback, evaporation modeling, and a hybrid SPH-grid representation for efficient combustion simulation. We validate our method through numerous experiments, demonstrating versatility in both indoor and outdoor fire scenarios.
