This data set is a supplementary resource for the article "Numerical Fire Spread Simulation Based on Material Pyrolysis - An Application to the CHRISTIFIRE Phase 1 Horizontal Cable Tray Tests", published by the peer-reviewed open access journal Fire. It is part of the "Fire Propagation in Cable Tray Installations" project. The provided data is only a summary of the full data produced for the article, due to its size. This article was previously submitted to the Fire Safety Journal and got eventually rejected. The information is structured into multiple *.rar archieves, which mimic the sub-directory structure created for the work. To be able to run the analysis scripts without much tweaking, extract all archieves into the same directory, with each archieve being a sub-directory in it. The data set is comprised of: The PROPTI and FDS input files used for the inverse modelling process (IMP) -- the 13* archieves. Full FDS simulation data of the mirco-combustion calorimeter (MCC) simulations of the best parameter sets per generation of the IMP runs, for jacket and insulator materials. Full FDS simulation data of the Cone Calorimeter simulations of the best parameter sets per generation of the IMP runs, for all three (25 kW/m², 50 kW/m², 75 kW/m²) incident heat flux conditions. FDS input files for the MT3 simulations, but full data only for the best parameter sets per IMP run (see below). Jupyter notebooks used for the analysis of the simulation responses including the scripts and plots generated for, and used in, the paper (RunReports). A general information directory, containing the FDS input file templates, experimental data used as target and Python scripts containing helper functions. Videos of a qualitative comparison of the SmokeView animation of the best parameter set in a cable tray simulation against a video from the experiment and an animation of the GAUGE_HEAT_FLUX development for the same simulation over the course of the simulation. Due to the size of the MT3 simulation data, only the FDS input files for the best parameter sets per generation are uploaded. Complete FDS simulation data is only provieded for the best perameter set of each IMP run, these are : IMP run, best rep. -------------------------------- imp_13b, 110751 imp_13c, 121106 imp_13d, 137738 imp_13e, 97493 imp_13f, 91988 imp_13g, 86988 imp_13h, 17480 imp_13b_1, 19033 imp_13b_2, 25043 imp_13b_3b, 24149 imp_13b_4, 29666 imp_13h_1, 10685 imp_13h_2, 10024 imp_13h_3, 10109 imp_13i, 13253 Note: The individual runs of the IMP are named differently as compared to the labeling used in the paper, as described below: IMP run, label in paper -------------------------------- imp_13b, Tb imp_13c, Ta imp_13d, Tc imp_13e, Ta,b,c imp_13f, Tb,c imp_13g, Ta,c imp_13h, Ta,b,cLA,L1,HC imp_13b_1, TbL1 imp_13b_2, TbPL1 imp_13b_3b, TbPL1L1 imp_13b_4, TbPL2,HT imp_13h_1, Ta,b,cPA,L1,HCL1 imp_13h_2, Ta,b,cPA,L1,HCL2 imp_13h_3, Ta,b,cPA,L1,HCL3 imp_13i, TbPA,L1,HC Version 2 changes: Added pre-print. Version 3 changes: Added new files that where produced during the revision process, after the original manuscript got rejected by the Fire Safety Journal. This revision corresponds to the intitial manuscript that was submitted to the journal Fire. The respective Zip archieves are labeled with a "_Revision01".
