“…It should be emphasized that the intended application of these parameters is equivalent to, but hopefully more general than, simply measuring energy release rate per unit area [2]. In any case any attempt to short-cut correlation analyses between test method data and large fires by ignoring important features of a particular fire scenario will not be successful.…”

“…Smith [2], Tewarson [3], and Parker [4] are among those who have developed devices to measure the transient rate of energy and other products of combustion from burning materials. These devices are flow-through systems in which measurements in the gas stream flowing from a burning specimen are used to infer the energy and product releases of the material.…”

Selecting an ignition criterion methodology for use in a radiative fire spread submodel

et al. 2010

SUMMARYResearch is ongoing to increase the functionality of the fire zone modeling software BRANZFIRE, by converting it from a deterministic to a probabilistic model. One component of this work is the development of a radiative fire spread submodel for which a suitable ignition criterion method is needed. This paper provides details of that ignition criterion procedure and its implementation into the submodel.A list of requirements that the ignition methodology had to satisfy was established. Of the many different piloted ignition models available, the Flux-Time Product technique, and its associated ignition criterion, was selected to be incorporated into the fire spread submodel. This method provides a practical engineering approximation of when a secondary fuel item that is subjected to incident radiation will ignite that is commensurate with the accuracy of the overall model.Primarily to demonstrate the use of the technique in the submodel, a series of ignition experiments were conducted on a single example of upholstered furniture using the Cone Calorimeter apparatus, with specimens tested in both the horizontal and vertical orientation, under piloted and auto ignition conditions. The experimental incident radiation and time-to-ignition data, for the piloted ignition mode, was analyzed using a modified Flux-Time Product correlation procedure.To deal with the auto ignition mode, an empirical approximation, based on the modified Flux-Time Product procedure, is proposed. Data for use in the submodel was therefore also derived for the auto ignition mode, based on an experimental determination of the minimum ignition flux.

This study aims to give an overview over different reaction-to-fire prediction models developed over the last decades by finding similarities and differences between models, as well as identifying their robustness in scaling. The models have been divided into four categoriesempirical, thermal, polynomial and comprehensivedepending on how pyrolysis is modelled. Empirical models extrapolate bench-scale test results to larger scales. These models are pertinent to applications that they have been validated for, but surfacic parameters used may not be scalable. In thermal models, pyrolysis is represented by heat transfer rates. The models are feasible for materials with high activation energies and where little pyrolysis occur before ignition. Polynomial models are empirical models that also take the environment into account. The validity of scaling is yet to be established. The comprehensive methodology includes chemical kinetics in the condensed phase. It has the potential to be used for any application; however, many parameters are needed. This increases the degrees of freedom versus data available for the description of the problem. Consequently, possible errors are introduced, and uncertainty is increased. A comprehensive multi-scale methodology is a way forward, where many steps of validation are possible.
