Uncertainty and Risk Analysis in Fire Safety Engineering
… occupants in, for example, a building in which a fire has broken out. The extended QRA considers the inherent uncertainty in the variables explicitly. The standard QRA does not consider the uncertainties in the variables and must be complemented by a sensitivity analysis or an uncertainty …

Decision Analysis in Fire Safety Engineering - Analysing Investments in Fire Safety
… methods to the evaluation of investments in fire safety was investigated, particularly with the aim of being able to suggest a method for analysing a specific investment in fire safety for a specific factory. Attention was directed above all at the handling of cases of large epistemic …

Development of pyrolysis models of composite materials for fire safety engineering
… the suitability of ThermaKin for novel fire retarded samples, under different thermal and fire conditions. The thermal decomposition of materials was investigated using simultaneous thermal analysis technique (STA) coupled with Fourier Transform Infrared Spectrometry (FTIR) at different …

An investigation into data sharing between building information modelling and fire safety engineering, with potential applications to smart buildings
… whole building lifecycle in the Architecture, Engineering and Construction (AEC) industry that suffers from existing problems such as data loss and incompatibilities on building projects. For Fire Safety Engineering (FSE)which is a safety support discipline, BIM presents an opportunity of …

Evacuation Modelling of Mixed-Ability Populations in Fire Emergencies
… that a significant percentage of fatalities in fires have suffered from some kind of disability. In this context 'disability' relates to a person's physical or mental condition that impinges on their ability to react and move promptly in an emergency. Various evacuation modelling techniques are …

Demand for Extinguishing Media in Manual Fire Fighting
… and intervention planning are important in fire prevention and risk management strategies. This study has shown that it is possible to use fire safety engineering models to estimate the development of fires on a realistic scale, and the corresponding requirement for extinguishing media. Data …

Flamelet modelling of soot formation in diffusion flames
In this work the steady and unsteady flamelet models have been applied to soot formation in laminar and turbulent diffusion flames. The aim was to study how different model parameters affect soot formation in diffusion flames. It was shown that certain assumptions are more crucial in laminar …

Experimental and numerical studies of whirling fires
… understand the physical mechanisms of whirling fires that occur in an open space and within enclosures. Buoyant whirling flames may be potentially more destructive than ordinary fires due to greater burning rate, higher concentration of heat release in a small region of the plume core, increased …

An investigation into automation of fire field modelling techniques
… thesis has produced a prototype system based on fire field modelling techniques for use by members of the Fire Safety Engineering community who are not expert in modelling techniques. The system captures the qualitative reasoning of an experienced modeller in the assessment of room geometries in …

The effect of physical properties on flame spread behavior for various paper/bagasse composition
Fire Safety Engineering is an application of science to improve the safety from the destructive effect of the fire. Paper is well known as a material that can easily catch fire. Nowadays, many researchers have been interested to produce paper by using other natural fiber to reduce the usage of wood …

Rail Tunnel Evacuation
In this thesis, human behavior in rail tunnel fires is explored. Descriptive knowledge is presented related to the evacuation of passenger trains, and the subsequent tunnel evacuation to a safe location. More specifically, a theoretical framework that can aid the understanding of human behavior is …

Time varying probability of failure of steel floor beams subjected to real fire
… reliability of steel beams under real fire conditions has been developed. It gives a more rational basis than time of failure modelling does for design. From risk modelling, some small resistance time from the probabilistic distribution times of failure can be deduced, which gives an …

Uncertainty in Quantitative Risk Analysis - Characterisation and Methods of Treatment
… risk analyses, used in decision making in safety-related issues (for instance, in land use planning and licensing procedures for hazardous establishments and activities) are presented and discussed, together with the different types of uncertainty that are introduced in the various stages …

Risk and Vulnerability Analysis of Complex Systems: a basis for proactive emergency management
The present thesis concerns methods and knowledge that are useful when analysing the risks and vulnerabilities of complex systems in a societal emergency management context. Operational definitions of vulnerability and emergency response capabilities are suggested and two methods for analysing the …

Predicting toxic gas concentrations resulting from enclosure fires using the local equivalence ratio concept linked to fire field models
Fire field modelling is based on the techniques of computational fluid dynamics (CFD), which provide detailed variable solutions throughout the computational domain quickly, repeatedly and cheaply compared with fire experiments. A main component of fire effluent are toxic gases and one of the main …

The generation of carbon monoxide in compartment fires
For the purpose of fire analysis and fire safety engineering, the development of empirical correlations for major species yields in compartment fires has become an important priority due to the inability to calculate these quantities from first principles. Studies of simplified upper layer …

Modelling of premixed laminar flame propagating in channels
The dynamics of the intrinsically unstable premixed flames propagating in channels is studied by means of numerical modelling in this work. Critical conditions of extinction and the influence of the thermal-diffusive effect on the dynamics of flame propagating in planar channels with cold sidewalls …

Effect of lining thermal inertia on small-scale compartment fire
The use of small scale facilities in experimental fire research studies is well estabhshed. This thesis concerns the use of small scale facilities to examine principally the influence of thermal inertia of the lining material on ventilated enclosure fire The radiation error of the thermocouple …
