“…In the majority of CFD simulations of CC tests for both charring [31,32] and noncharring materials [33][34][35], participation of the gas phase in radiative heat transfer is neglected [31][32][33]. In order to eliminate errors associated with the use of this simplifying assumption, a detailed simulation approach is followed by taking into account gas phase radiation phenomena between the cone heater and the material surface.…”

“…The accuracy of this model was verified by comparing conductive and radiative transfer, mass transport, and chemical reaction simulations to the corresponding analytical solutions [4]. This model was also shown to be able to capture experimentally observed burning behavior of a wide range of materials [6,7,20].…”

Quantitative understanding of the processes that take place inside a burning material is critical for the prediction of ignition and growth of fires. To improve this understanding and enable predictive modeling, we developed a numerical pyrolysis solver called ThermaKin. This solver computes transient rate of gaseous fuel production from fundamental physical and chemical properties of constituents of a pyrolyzing solid. It was successfully applied to the simulation of combustion of a broad range of materials. One limitation of ThermaKin was that it could handle only one-dimensional burning problems. As a consequence, flame spread, which is an important contributor to fire growth, could not be simulated. Here, we present a new computational tool, ThermaKin2D, that expands ThermaKin model to two dimensions and combines it with a flexible analytical representation of a surface flame. It is our expectation that this tool will enable highly accurate simulations of flame spread dynamics. This manuscript contains a description of this new computation tool, reports results of a series of verification exercises, and demonstrates some of the ThermaKin2D's capabilities. Published 2013. This article is a U.S. Government work and is in the public domain in the USA.

“…In fact, the flame heat flux is simply estimated by fitting the cone calorimeter heat release rate for a single external irradiance level. Quantitative predictions are improved when using heating curves specific of each irradiation level . On the other hand, the flame heat fluxes seem to depend not only on the specific material properties but also on the estimation method (for instance, 10 kW/m 2 [Patel et al], 11‐15 kW/m 2 [Stoliarov et al and Patel et al], or 16‐47 kW/m 2 [Spearpoint and Quintiere]).…”

Summary The total net heat flux of the flame from a burning solid fuel is an important issue for the formulation of comprehensive solid‐phase models useful for the fire testing of materials, but measurements are often affected by significant inaccuracy. In this study, an evaluation is conducted using a state‐of‐the‐art model, coupling the descriptions of both gas‐ and solid‐phase processes, for a thick poly(methyl methacrylate) slab burning in a cone calorimeter. It is observed that the total net heat flux (conductive and radiant flame heat fluxes minus surface reradiation losses) remains approximately constant (about 18 kW/m2) as the intensity of the cone irradiance increases from 15 to 60 kW/m2. The influences of some model assumptions and the solid degradation kinetics on this process variable are also assessed. Acceptable agreement is obtained between the predicted and the measured mass loss rates.
