CFAST is a two-zone fire model capable of predicting the environment in a multi-compartment structure subjected to a fire. It calculates the time evolving distribution of smoke and fire gases and the temperature throughout a building during a user-

Natural gas a hydrocarbon gas mixture that consists primarily of CH4 is perceived as transition fuel due to its high energy density and lower greenhouse gas (GHG) emissions during combustion relative to coal and oil. However, considering the life

Methane (CH4) is one of the major greenhouse gases with a CO2relative global warming potential above 20 over a 100-year period (IPCC TAR). Global average concentration of this tracer in Earth's atmosphere is increasing due to widely spread surface sources
In evacuation models, the time between the first alarm or other initial cue until the population starts evacuating, often referred to as the pre-evacuation time or pre-movement time, is usually a user defined input. To address this deficiency, this paper

This paper provides an analysis of the evacuation of the World Trade Center towers culled from telephone and face-to-face interviews with survivors. A decedent analysis explores where occupants were located when each tower was attacked. Multiple regression
Methane is one of the major greenhouse gases and in recent years more efforts have been undertaken to estimate its emissions at local and regional scales utilizing new observing systems. During 2012, Earth Networks Inc. deployed a dense GHG observing

Currently, inverse atmospheric dispersion models are being used around the world to provide measurement-based, or top- down, estimates of greenhouse gas (GHG) emissions for comparison with input-based, or bottom-up, estimates. To minimize uncertainty

A well-known challenge for large eddy simulation (LES) is to provide a smooth transition from molecular to turbulent transport near the wall without having to explicitly resolve the viscous sublayer. We propose a simple but efficient approach based on

A review is presented of the state of the art of smoke production measurement, prediction of smoke impact as part of computer-based fire modeling, and measurement and prediction of the impact of smoke through deposition of soot on and corrosion of
Fire simulation tools are used frequently in the fire safety assessment of nuclear and other industrial installations. They are also used in the context of probabilistic fire risk assessment as deterministic models providing the relation between the random

A systematic approach to the identification of fire-safety scenarios for analysis is desirable in order to identify important scenarios and to help ensure a consistent approach for different analysts. The number of possible fire-safety scenarios in any
