Probabilistic Modelling of Sensitivity in Fire Simulations
… the emerging field of toxic hazard simulation in fire science. Fire simulation based on computational fluid dynamics (CFD) plays an important role in performance-based fire design. However, the thermal-physical process of material decomposition in fires and the chemical reactions of fire effluents …

Development of Hybrid Fire Simulation Methods and Their Applications to Column Fire Tests
The design philosophy in structural fire design has been shifting from prescriptive design toward performance-based design. The hybrid fire simulation method, where a physical element and a numerical model are integrated, can be used to combine the benefits of the element-level fire test and …

Predicting Large Domain Multi-Physics Fire Behavior Using Artificial Neural Networks
Fire dynamics is a complex process involving multi-mode heat transfer, reacting fluid flow, and the reaction of combustible materials. High-fidelity predictions of fire behavior using computational fluid dynamics (CFD) models come at a significant computational cost where simulation times are often …

Advanced Computing and Sensing to Improve Mine Fire Characterization and Response
After fire is discovered in an underground coal mine, a decision must be made to mitigate fire consequences. The decision should be made based on existing conditions, with the goal of increasing the probability of fire extinguishing without compromising the health and safety of the firefighting …

Fire safety risk model for a main vertical zone of a large passenger ship
… shed light on the everlasting issue of on-board fires, witha particular focus on large passenger ships, by proposing a fire risk model for a MainVertical Zone (MVZ). Historically, fire had and always has been a pressing accidenttype, along with flooding. Despite the regulatory effort, the total …

SPATIAL VARIABILITY IN FOREST FUELS: SIMULATION MODELING AND EFFECTS ON FIRE BEHAVIOR
… in fuel beds and an increasing human population. Fire management policy emphasizes fuel treatments, such as thinning and prescribed burning, to remedy this situation because fuels are the one component of the problem that we can directly affect through management action. At present, however, the …
