Computational investigation of flahover mechanisms using fire dynamics simulator (fds)
… of the development of flashover in enclosure fires was performed using the Fire Dynamics Simulator (FDS) platform. Practical criteria for flashover commonly proposed in the literature were investigated in the context of FDS modeling to determine similarity between the CFD model, previous …

Estimating the Heat Transfer from an Electric Vehicle Fire using Fire Dynamics Simulator
… thesis guidelines for modeling a vehicle using Fire Dynamics Simulator (FDS) and its relevant parameters are explored and documented through an estimation and comparison to experimental data. Vehicle construction consists of determining fire spread and subsequent burner delineation from analysis …

Visualising convective heat transfer in a propagating wildland fire
Bushfires are a large destructive natural hazard, intensified by climate change and increasing human activity into wildland areas. Accurate prediction of fire behaviour is essential for mitigation strategies and emergency response. While radiative heat transfer has traditionally been emphasized in …

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 …

Computational Study of Highway Bridges Structural Response Exposed to a Large Fire Exposure
The exposure from a localized vehicle fire has been observed to produce excessive damage onto highway bridge structural elements including complete collapse of the infrastructure. The occurrence of a fire beneath a bridge can lead to significant economic expense and loss of service even if the …

Effects of Wool Fibres on Mechanical and Flammability Characteristics of Wool-Polypropylene Composites
… performance. Also, wool is a naturally fire resistant fibre because of its high nitrogen and sulphur contents as well as char forming ability. In spite of the advantages of wool, studies regarding wool based polymeric composites have not been thoroughly performed. Therefore, this thesis …

Advancing Coupled Fire-Atmosphere Simulation: Fuel Representation and Fire Spotting
Wildland fires can lead to substantial ecological, social, and economical losses as well as health burdens due to smoke produced from biomass burning. Accurate wildland fire simulation is an essential capability in predicting and managing these losses, benefiting both pre-fire risk mitigation and …
