Proceedings of the first workshop organized by the IAFSS Working Group on Measurement and Computation of Fire Phenomena (MaCFP)

Abstract

This paper provides a report of the discussions held at the first workshop on Measurement and Computation of Fire Phenomena (MaCFP) on June 10–11 2017. The first MaCFP work-shop was both a technical meeting for the gas phase subgroup and a planning meeting for the condensed phase subgroup. The gas phase subgroup reported on a first suite of experimental- computational comparisons corresponding to an initial list of target experiments. The initial list of target experiments identifies a series of benchmark configurations with databases deemed suitable for validation of fire models based on a Computational Fluid Dynamics approach. The simulations presented at the first MaCFP workshop feature fine grid resolution at the millimeter- or centimeter- scale: these simulations allow an evaluation of the performance of fire models under high-resolution conditions in which the impact of numerical errors is reduced and many of the discrepancies between experimental data and computational results may be attributed to modeling errors. The experimental-computational comparisons are archived on the MaCFP repository [1]. Furthermore, the condensed phase subgroup presented a review of the main issues associated with measurements and modeling of pyrolysis phenomena. Overall, the first workshop provided an illustration of the potential of MaCFP in providing a response to the general need for greater levels of integration and coordination in fire research, and specifically to the particular needs of model validation.

On the use of dynamic turbulence modelling in fire applications

“…The experiments considered here for validation purposes are all test cases of the MaCFP workshop [12] (https://iafss.org/macfp/) and were chosen by the authors since they have been identified by the fire community as the 'best' cases, at least to date, for CFD validation. A detailed description of the different test cases is already available (https://github.com/MaCFP), hence, only a brief overview is outlined here.…”

Call for Participation in the Second Workshop Organized by the IAFSS Working Group on Measurement and Computation of Fire Phenomena

“…The workshop served as a first technical meeting for the gas phase subgroup and a planning meeting for the condensed phase subgroup. The program of the workshop and copies of the presentations can be found at https://iafss.org/3770-2/; the proceedings that report on the content and main outcomes of the workshop were published in Fire Safety Journal [1].…”

Automated fitting of thermogravimetric analysis data

“…An example of a public database of material properties is found in the Validation Guide of the Fire Dynamics Simulator (FDS) 5 . Currently, an international effort is underway to further develop experimental and modeling tools such as these in order to “advance predictive fire modelling” 6 . The present manuscript presents work based on a coordinated effort to develop a comprehensive database of material properties for use in fire models.…”

“…5 Currently, an international effort is underway to further develop experimental and modeling tools such as these in order to "advance predictive fire modelling". 6 The present manuscript presents work based on a coordinated effort to develop a comprehensive database of material properties for use in fire models. This database will include both raw data from a suite of milligram-scale tests and a list of properties for each material that could be directly used as inputs for a fire model such as FDS.…”
