Hydrogen addition is known to improve the stability of highly strained hydrocarbon premixed flames. Since the flame temperature is an important factor associated with extinction, it is of interest to study the thermal ...

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 ...

The objective of this work is to develop a predictive activation time algorithm for smoke plumes for axonX's SigniFire video image detection (VID) system from recent tests in a large volume space performed at the University ...

This paper presents an investigation of the structural response of a long span cellular beam with varying section geometries while subject to various temperature-time curves. This type of beam is under investigation, in ...

Scale modeling affords engineers the ability to appreciate the dynamic enclosure fire environment of larger than life structures in the laboratory. Conventional approaches to scaling have expressed results in terms of ...

Compartment fires with different ventilation conditions exhibit different dynamical behaviors, ranging from steady fuel-limited fires to unsteady air-limited fires. Numerical simulations are here performed to study compartment ...

Positive Pressure Ventilation (PPV) is a tactic that is used on fire grounds across the world everyday, both to improve tenability after the extinguishment of a fire and/or offensively during fire attack to improve ...

This thesis considers fire hazards in the existing vehicle fleet and uses failure modes and effects analyses of three generic designs to identify and rank potential fire hazards in the Emerging Fuel Vehicle (EFV) fleet. A ...

Many of the clean agents currently used in total flooding fire suppression applications have vapor densities greater than ambient air. The denser agent-air mixture creates hydrostatic pressure differences causing flow of ...

A Cone Calorimeter device has been used to measure the flammability properties of samples with different clay dispersion on the nanometer (molecular) scale. Specifically, chemical energy release rate, mass loss rate, and ...
