Flame Extinction and Air Vitiation Effects In FDS In Poorly Ventilated Compartment Fires

Compartment fires with different ventilation conditions exhibit different dynamical behaviors, ranging from steady fuel-limited fires to unsteady air-limited fires. Numerical simulations are here performed to study compartment fires in a configuration corresponding to a scaled-down model…
