MaCFP Condensed Phase Phenomena

Background

The MaCFP Working Group and workshop series was created in 2015 and the call for participation in the first workshop was issued in April 2016. Continuously updated information on the MaCFP Working Group effort can be found at: http://www.iafss.org/macfp/

Following discussions that took place in April 2016, it was proposed that the MaCFP Working Group be expanded to include a subgroup dedicated to the predictive modeling of condensed phase phenomena. A committee was formed to produce a white paper and organize a planning meeting during the first MaCFP workshop conducted in Lund, SE at the 2017 IAFSS meeting.

The program of the 2017 workshop, copies of workshop presentations, and the proceedings that report on the content and main outcomes of the workshop (published in the Fire Safety Journal) can be found at the links below:

Objectives

The purpose of the Condensed Phase Phenomena subgroup is to facilitate data sharing and model development to improve computational predictions of thermal degradation and pyrolysis in fire scenarios. The specific objectives of the subgroup are to:

Develop standard data set formats for experimental data on pyrolysis;
Develop requirements for data set quality and establishing a data review committee;
Incorporate compliant data into the existing MaCFP data repository;
Create a database of pyrolysis property sets;
Develop minimum requirements for numerical pyrolysis models;
Organize a pyrolysis modeling discussion group.

Virtual Discussion Forum

A Google Discussion Group for the Condensed Phase subgroup of the MaCFP Working Group can be accessed here: MaCFP Virtual Discussion Forum. The purpose of this forum is to facilitate data sharing and model development to improve computational predictions of thermal degradation and pyrolysis in fire.

Experimental Measurements Submitted to the 2021 Workshop

A preliminary report summarizing the experimental measurements submitted to the 2021 Condensed Phase MaCFP Workshop has been prepared. This report contains:

Brief descriptions of all experiments conducted and test conditions used
A summary of all measurement data, presented/separated by experiment type and test conditions
Calculations of error for each dataset
Calculations of ‘average’ curves / datasets (neglecting obvious outliers)
A preliminary (brief) analysis and comparison of experimental results

The 2021 MaCFP Condensed Phase Workshop

UPDATE – Because of concerns and travel restrictions associated with the Coronavirus (COVID-19) pandemic, the second MaCFP workshop has been postponed to April 22-23, 2021, and will take place as a pre-event to the 13th IAFSS Symposium in Waterloo, Canada (http://iafss2020.ca).

The four main objectives of this workshop are listed as follows:

To catalogue current approaches used to parameterize pyrolysis models;
To quantify the interlaboratory variability for comparable experimental datasets;
To assess the impact of the variability of model parameters on predictions of sample burning rate; and
To present a rigorous analysis of these results in the Fire Safety Journal
