In warehouse storage applications, it is important to classify the burning behavior of commodities and rank them according to material flammability for early fire detection and suppression operations. In this study, the large-scale effects of warehouse fires are decoupled into separate processes of heat and mass transfer. As a first step, two nondimensional(More)
We describe an automatic quadrature routine which is specifically designed for real functions having a certain type of infinite oscillating tails. The algorithm is designed to integrate a vector function over an infinite interval. A FORTRAN implementation of the algorithm is included. The algorithm combines an adaptive subdivision strategy with(More)
It consider the problem of computing efficient strategies for Searching. As a generalization of the classical binary search for ordered array, suppose one wishes to find a specific element in an ordered array by making comparisons, where each comparison indicates the endpoint closer to the desired element. Given the likelihood of each element being the one(More)
Fire models are routinely used to evaluate life safety aspects of building design projects and are being used more often in fire and arson investigations as well as reconstructions of firefighter line-of-duty deaths and injuries. A fire within a compartment effectively leaves behind a record of fire activity and history (i.e., fire signatures). Fire and(More)
In fire models, the accurate prediction of aerosol & soot concentrations in the gas phase and aerosol & soot deposition thicknesses in the condensed phase is important for a wide range of applications, including human egress calculations, heat transfer in compartment fires, and forensic reconstructions of fires. During a fire, in addition to soot transport(More)
Soot concentrations are generally over predicted during the typical application of fire models. The addition of soot deposition and gravitational settling mechanisms to Fire Dynamics Simulator (FDS) results in improved predictions; however, those predictions are highly dependent upon assumptions of soot particle size. Large particle sizes appear to be(More)
