Fire Engineering Projects

This work emphasizes the importance for egress model users to choose a model for each project with the appropriate input features and simulation capabilities. This report also gives model users a mechanism for choosing the appropriate model by providing a ...

Aqueous Film Forming Foam has been a fire suppression agent in use for nearly forty years. During this period, there has been little emphasis on characterizing the flow from nozzles that have a throw of only a few meters. With ...

Title: Numerical Simulation of Ignition and Transient Combustion in Fuel Vapor Clouds The Large-Eddy Simulation (LES) approach is used to model partially-premixed combustion (PPC) in confined and unconfined fuel vapor clouds. The model is based on the concept of a filtered ...

A combined analytical and experimental study was performed to produce and validate a method by which the lengths and widths of flames burning on wax candles can be predicted. Two analogies are drawn: first, that heat transfer from the wick ...

This work investigates the thermal transient response of different soils when exposed to intense heat flux. A special porous media code, TOUGH2, is applied for numerical analyses. Improvements are made to previous experimental facilities, and new experimental results are used ...

This investigation provides a detailed analysis of the hydraulic analogue technique used as a predictive tool for understanding smoke detector response within a complex enclosure. There currently exists no collectively accepted method for predicting the response of smoke detectors; one ...

This study investigates the effects of heating on the transient behavior of the geologic media surrounding the tunnel involved in a severe fire, which typically involve extreme temperature and prolonged duration. Currently, there is little research being done in this ...

Title: AN ASYMPTOTIC ANALYSIS OF SPONTANEOUS IGNITION OF HYDROGEN JETS Analytical work is presented for the spontaneous ignition of a hydrogen jet emanating from a slot into air. A similarity solution of the flowfield was obtained. This was combined with the ...

A new scaling technique based on the hypothesis that flows in a compartment fire are buoyancy driven was introduced by Quintiere [4]. Based on this hypothesis, scaling relations for convective and radiative heat transfer within compartment fires is presented. A ...

Approximation methods exist to provide estimates of smoke detector response based on optical density, temperature rise, and gas velocity thresholds. The objective of this study was to assess the uncertainty associated with these estimation methods. Experimental data was used to ...
