ABSTRACT
1604907 - Trouve
The general objective of the research project is to build an international collaborative framework between computational and experimental researchers in the fire science community around the topic of the experimental validation of computer-based fire models. The fire science community is small, fragmented and geographically dispersed. The present project is an effort to meet the resulting organizational challenge, to promote high levels of integration and coordination, and to provide a critical mass of researchers for topics central to computational fire research. The project will build on established programs in the U.S. aimed at producing computer models for engineering analysis of building fires, e.g., the Fire Dynamics Simulator developed by the National Institute of Standards and Technology and FireFOAM developed by FM Global. The project will contribute data and software modules to a new open-access web-based repository, develop physics-based guidelines for computational best practices, and produce a new series of online tutorials for graduate-level students. The project will also advance fundamental knowledge and develop engineering-level tools for the generic problem of fire spread along solid flammable materials.
The project is proposed as part of a new initiative led by the International Association for Fire Safety Science (IAFSS) called "the IAFSS Working Group on Measurement and Computation of Fire Phenomena" (or the MaCFP Working Group). On the technical side, the project will focus on the problem of turbulent wall flames supplied with fuel vapors produced by the thermal degradation of solid flammable materials. The project will include performing both fine-grained (research-level) and coarse-grained (engineering-level) large eddy simulations. Coarse-grained simulations will require the development of new wall models for turbulent boundary layer flames. The simulation software adopted in the project is the free open-source fire model called FireFOAM. On the organizational side, the project will support the MaCFP Working Group effort, develop an open-access web-based digital archive of well-documented numerical simulations corresponding to selected target experiments, help identify key research topics and knowledge gaps in computational and experimental fire research, develop best practices in computational fire research, contribute to the organization of the new MaCFP workshop series, and help develop an international network of fire researchers and a community-wide forum for discussion and exchange of information.

PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
This project has allowed the development of a collaborative framework between computational and experimental researchers in the fire science community around the topic of the experimental validation of computational fire models.
On the technical side, the project has explored the relevance and potential of advanced turbulent combustion and radiation models in a series of computer simulations of laboratory-scale methane flames and methanol flames previously studied experimentally at the University of Maryland, University of Waterloo (Canada) and the US National Institute of Standards and Technology. The simulations were performed at high (i.e., millimeter-scale) resolution in order to unravel the complex interactions between turbulence, combustion and thermal radiation processes. The simulations suggest that current computational fire models can predict the intensity of the gas-to-fuel-surface thermal feedback with a 25% accuracy. These results open the route to future simulations of more elaborate configurations with solid fuels and flame spread.
On the organizational side, the project has allowed the development of an international network of fire researchers, called ?the IAFSS Working Group on Measurement and Computation of Fire Phenomena? (or the MaCFP Working Group, see http://www.iafss.org/macfp). The MaCFP Working Group is an open, community-wide, international collaboration between fire scientists, with data and information posted on a dedicated website (http://www.iafss.org/macfp) and a GitHub repository (https://github.com/MaCFP). The repository contains experimental and computational data for an initial list of eight target experiments pre-selected for their quality and relevance to fire model validation. The MaCFP Working Group is organized around a series of workshops with the next workshop scheduled to take place as part of the 13th Symposium of the International Association for Fire Safety Science (IAFSS) in April 2021(http://iafss2020.ca).
