The simulation of fire growth and spread within enclosures using an integrated CFD fire spread model
… within a CFD software framework to simulate fire in a compartment and fire growth and propagation in enclosures in which solid combustibles are involved through wall or ceiling linings. Gas phase combustion, radiation and solid fuel combustion are addressed in this study. At the heart of this …

Fire safety evaluation of multifunctional buildings - Special emphasis on antagonistic attacks and protection of sensitive areas
… new, not previously well analyzed problems for fire safety. A method for selection and evaluation of fire scenarios in multifunctional buildings has been developed. The evaluation method is based on the performance-based design approach, using scenario analysis, and accounts for specific …

Stochastic Modelling and Optimal Control of Compartment Fires
Compartment fires are defined as fires in enclosed spaces. They are labeled as oxygen driven fires and are non-stationary growth phenomenon. A gap exists in the knowledge of deterministic fire growth models and stochastic fire growth models. In this thesis we develop non-stationary stochastic …

Uncertainty and sensitivity analysis of a fire-induced accident scenario involving binary variables and mechanistic codes
… (NRC) to a risk-informed, performance-based fire protection rulemaking standard, Fire Probabilistic Risk Assessment (PRA) methods have been improved, particularly in the areas of advanced fire modeling and computational methods. As the methods for the quantification of fire risk are improved, …

Fire Response of Loaded Composite Structures - Experiments and Modeling
… response and failure of loaded, fire-exposed composite structures was studied. Unique experimental equipment and procedures were developed and experiments were performed to assess the effects of mechanical loading and fire exposure on the service life of composite beams. A series …

Prediction of water droplet behaviour during fire extinguishment
Sprinklers have been used in fire suppression for about 100 years. Even though their design has changed from simple perforated pipes to sophisticated automatic systems of mist and sprinkler nozzles, still they play the same role - they dramatically reduce death and injuries due to fire, as well as …

Theoretical and Experimental Study on Fully-Developed Compartment Fires
To predict the effect of fire on the structures, one needs to understand physics of the fire growth in a compartment as to how the fuel interacts with the flame and its surroundings. This study explores these effects and applies them to the common fuel configurations such as pool and crib fires. …

Numerical Modeling of Turbulent Combustion and Flame Spread
… flames, flame heat transfer and flame spread in fires. The gas temperature and velocity, soot volume fraction, wall surface temperature, char depth, radiation and convection heat fluxes, and heat release rate were calculated and compared with experimental measurements. In addition, to provide …

Modeling full-scale fire test behaviour of polyurethane foams using cone calorimeter data
… use of these polymeric materials causes fire safety concerns. This has led to the development of various regulations and flammability test standards aimed at addressing the hazards associated with polyurethane foam fires. Several fire protection engineering correlations and thermal models …

Large Eddy Simulation of Boundary Layer Combustion
… including but not limited to the occurrence of fire spread, as a result of a heating load to a flammable wall leading to fire growth in enclosure settings; and in engine combustion configurations where the interaction with a cooled surface combined with occurrences of short flame wall distances …

Fire modelling of passenger trains
ENGLISH ABSTRACT: Train fires continue to pose a significant threat both internationally and in South Africa, particularly with the increasing prevalence of emerging hazards such as lithium-ion battery devices carried by passengers. With the introduction of the new X’Trapolis Mega fleet, it is …

Computational Study of Parameters Affecting Electric Cabinet Fire Heat Release Rate
Electrical cabinet fires occur frequently in commercial and industrial facilities. However, the severity of these fire events varies widely, making it difficult to estimate the fire growth and size with certainty. This study aims to identify the significant parameters that affect electrical cabinet …

Development of fire retardant timber treatments
Fire retardant treated timber has been used in interior and exterior building structures to satisfy the legal flammability requirements. Dricon and NCX are two commercial phosphorus-based products sold by Arch Timber Protection. However, modifications to their formulation may be required due to …

Impact of high-rise morphology on gas temperatures during fires
With the development and use of fire sensitive construction materials and furnishings,and with the growing demand for high-rise development, there is an increasing need forimproved fire safety measures. Modern high-rise policies within the UK and USArequire a minimum fire safety standard. Current …
