CALL FOR PAPERS
Symposium on Obtaining Data for Fire Growth Models
December 9-10, 2021
Atlanta, GA
ABOUT THE EVENT
Papers are invited for a Symposium on Obtaining Data for Fire Growth Models to be held December 9-10, 2021. Sponsored by ASTM Committee E05 on Fire Standards, the symposium will be held in Atlanta, GA, in conjunction with the December standards development meetings of the committee.
Objective and Scope
In the mid-1990s ASTM E05 published Guide E1591 on obtaining data for fire models. Since the initial publication of the guide, our ability to simulate fires and quantify their effects has improved tremendously. This is partly due to the accessibility of ever-increasing computational power, which has allowed us to model physical and chemical fire phenomena with much greater fidelity. However, these advances have come at a price because users of the more sophisticated fire models of today need to provide a growing amount of input data, most of which are difficult to obtain. Although Guide E1591 has been updated several times over the years, it has not kept up with the revolutionary developments in fire modeling. The purpose of the proposed symposium is to bring researchers from around the globe together to present results of the most recent pertinent studies and participate in a discussion with the objective of developing a roadmap for positioning Guide E1591 to keep pace with 21st century fire modeling.
Possible topics are as follows:
- Methods for measuring or estimating thermophysical properties of simple and complex materials (k, r, c, and the often forgotten e) and approaches to account for temperature effects;
- Interpretation of Thermal Analysis (TGA, DSC) and Microscale Combustion Calorimeter (ASTM D7309) data to estimate the kinetic parameters, specific heat capacities, heats of combustion, and heats of transition for thermal degradation reactions in solids;
- Methods for estimating the heats of gasification and pyrolysis of solids;
- Methods for measuring dimensional changes of solids as a function of temperature and/or during transition to a different state (e.g. char) and approaches to account for these changes in heat conduction and pyrolysis models;
- Methods for measuring or estimating the soot yield and the yields of various products of combustion as a function of the environmental conditions in which the combustion takes place;
- Approaches for obtaining best-estimates of multiple “apparent” material properties based on optimization of agreement between mass loss rate predictions and measurements;
- Solutions to address challenges that are encountered when using small-scale calorimeter data to estimate input parameters for modeling (e.g., accounting for the heat flux from the flame to the surface on the burning rate of the specimen);
- Approaches for modeling opposed-flow flame spread and for obtaining the material properties that are needed;
- Methods for measuring or estimating the combustion efficiency and the convective and radiative fractions of the heat release rate from various materials and fuel packages.
