Towards a collaborative research infrastructure for fundamental studies of turbulent fire phenomena

1604907 - TrouveThe研究项目的总体目标是围绕基于计算机的火灾模型的实验验证这一主题，在火灾科学界的计算和实验研究人员之间建立一个国际合作框架。消防科学界规模小，分散，地理上分散。本项目是一项努力，以满足由此产生的组织挑战，促进高水平的集成和协调，并提供了一个临界质量的研究人员的主题中央计算火灾研究。该项目将建立在美国的既定计划基础上，旨在为建筑火灾的工程分析制作计算机模型，例如，美国国家标准与技术研究所开发的火灾动力学模拟器和FM Global开发的FireFOAM。该项目将为一个新的开放式网络储存库提供数据和软件模块，为计算最佳做法制定基于物理学的准则，并为研究生编制一系列新的在线教程。该项目还将推进基础知识和开发工程级工具，以解决火灾沿沿着固体材料蔓延的一般问题。该项目是国际消防安全科学协会（IAFSS）领导的一项新倡议的一部分，该倡议称为“IAFSS火灾现象测量和计算工作组”（或MaCFP工作组）。在技术方面，该项目将侧重于固体易燃材料热降解产生的燃料蒸汽供应的湍流壁火焰问题。该项目将包括执行细粒度（研究级）和粗粒度（工程级）大涡模拟。粗粒度的模拟将需要开发新的湍流边界层火焰的壁面模型。该项目采用的仿真软件是免费的开源火灾模型FireFOAM。在组织方面，该项目将支持MaCFP工作组的工作，开发一个开放访问的基于网络的数字档案，其中包含与选定目标实验相对应的记录良好的数值模拟，帮助确定计算和实验火灾研究中的关键研究主题和知识差距，制定计算火灾研究的最佳实践，为组织新的MaCFP系列研讨会做出贡献，并帮助建立一个火灾研究人员的国际网络和一个社区范围的论坛，以供讨论和交流信息。

1604907 - TrouveThe 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.
