A pyrolysis modelling approach was expanded to full-scale simulation of a cable tray fire. Earlier experimental thermogravimetric analysis (TGA) and cone calorimeter results were used to construct the pyrolysis model. For model validation, data form the CFSS-1 experiment of the OECD/NEA PRISME 2 project was used.
A state-of-the-art methodology for the simulation of the cable cone calorimetry with FDS wass proposed in this study. Cable geometry was modelled with cubic obstructions using the new 3D heat transfer (HT3D) and 3D pyrolysis (PYRO3D) routines of the FDS.
Effects of ageing on the thermal decomposition process of polyethylene using united-atom MD simulations were studied. Qualitatively, ageing had a very little effect on the shape and position of the simulated TGA curves, suggesting essentially no effect of ageing on pyrolysis of polyethylene.
