MaCFP-4 Program

Pre-workshop Guidelines for Participation

On March 28, 2025, the MaCFP Working Group organized a virtual meeting to share its Call for Participation in MaCFP-4 and to coordinate:

The experimental component of the MaCFP-4 Pyrolysis Model Calibration exercise, and
The modeling component of the MaCFP-4 Radiation Heat Transfer exercise.

The meeting provided an overview of how to participate in each case and allowed participants to ask follow up questions as needed. Details of these two exercises are provided in the Guidelines for Participation in MaCFP-4 Document (see below).

Guidelines for Participation in the MaCFP-4 Workshop

Thorough descriptions of the experimental experiments considered in the MaCFP-4 workshop, related workshop timelines (tentative), and a guide for communicating results is available: Guidelines_for_Participation_MaCFP-4.pdf. This copy (updated 16 Jan 2026) is available for download here as a .pdf; up to date copies of this document can be compiled from the documents section of the MaCFP Github Repo.

Submission of Experimental and Computational Results

A wiki page with instructions for submitting experimental results to the pyrolysis model calibration exercise is available online.

A video discussing the process is available as an asset to this release here.

Pyrolysis Model Validation (Pine Wood)

The MaCFP Condensed Phased Subgroup is organizing a pyrolysis model calibration exercise for a charring material: pine wood. No single approach is suggested for model parameterization. In fact, a key objective of this material property determination exercise is to catalog current approaches used to parameterize complex pyrolysis models. MaCFP-4 pyrolysis modeling targets will include only anaerobic conditions; however, participants are encouraged to develop experimental datasets and corresponding models that will describe oxidation (as will be studied in detail at MaCFP-5)

Experimentalists are asked to perform tests and share their measurement data to be made publicly available on the MaCFP GitHub Repository.
Modelers are asked to calibrate material property sets using this data and perform simulations of material response to heating (0D thermal decomposition and 1D gasification).

How to Request Samples

Limited quantities of the test material will be made available directly to participants who can commit to conducting certain experiments.
To request samples, members of the fire research community participating in the experimental component of the MaCFP-4 Workshop are invited to contact Dr. Isaac Leventon [National Institute of Standards and Technology (NIST), USA; isaac.leventon@nist.gov] and Dr. Mark McKinnon [UL Fire Safety Research Institute (UL FSRI), USA; mark.mckinnon@ul.org]. Please indicate the number and type (e.g., mg-scale thermal analysis and/or bench scale gasification experiments) of tests that you can commit to performing.

Templates for Submitting Experimental Results

Experimental and Modeling Results will be submitted, stored, and made publicly available in the appropriate folders and subfolders of the MaCFP GitHub Repository. Participants can submit their contributions by creating a pull request on Github. For simplicity, please organize all measurement data in a single folder with your INSTITUTE name. Template files (e.g., .json files holding material property information; .csv files holding experimental measurement data; and Markdown text files [README.md] that provide a description of the test conditions of all experiments conducted) are available on the Condensed Phase Github repository (matl-db).

Pyrolysis Model Validation (PMMA)

The MaCFP Condensed Phased Subgroup organized a pyrolysis model validation exercise to recommend a material property set for use in MaCFP-3 fire growth simulations. Experimental measurements, the results of this pyrolysis model validation exercise, and a recommended material property set were shared in a series of virtual meetings .
