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.

1604907-Trouve该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。本项目是为了应对由此产生的组织挑战，促进高水平的整合和协调，并为计算火灾研究的核心课题提供足够数量的研究人员。该项目将建立在美国现有项目的基础上，这些项目旨在为建筑火灾的工程分析生产计算机模型，例如由美国国家标准与技术研究所开发的火灾动力学模拟器和由FM Global开发的FireFOAM。该项目将向一个新的基于网络的开放式资料库提供数据和软件模块，为计算最佳做法制定以物理学为基础的指导方针，并为研究生编写一系列新的在线教程。该项目还将增进基础知识并开发工程级工具，以解决火灾沿固体易燃材料蔓延的一般问题。该项目是由国际火灾安全科学协会(IAFSS)领导的名为“IAFSS火灾现象测量和计算工作组”(或MaCFP工作组)的新倡议的一部分。在技术方面，该项目将重点解决由固体易燃材料热降解产生的燃料蒸气供应的湍流壁火问题。该项目将包括执行细粒度(研究级别)和粗粒度(工程级别)的大涡模拟。粗粒度模拟需要发展新的湍流边界层火焰壁面模型。该项目采用的模拟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，开发与选定目标实验相对应的有充分记录的数值模拟的开放式网络数字档案，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做法，促进新的MaCFP讲习班系列的组织，并帮助发展一个国际火灾研究人员网络和一个全社区讨论和交流信息的论坛。
