Development of a Cone Calorimter Fire Model for Validative Pyrolysis and Combustion Studies for Composite Materials

We develoepd a robust fire preditive tool using a large eddy simulation (LES) modelling framework to validate our pyrolysis and combustion kinetics data.

As an example, the two simulation case studies involving the fire developments of pure high-density polyethylene (HDPE_ foam and its chitosan/graphene oxide (CHT/GO) flame-retardant HDPE foam counterpart are presented. The numerical representation of the flame proves that the proposed pyrolysis kinetics framework and LES model was able to capture the effect of flame-retardants in the reduction of volumetric fire size, which also corresponds to the observations during the experiment.

​

The model is capable of capturing the surface regression and char formation layer of the solid degradation process of the materials. Enhance significance of char offered by the carbon-based flame-retardant GO is well-demonstrated in this study via the rapid increase in char density and layer height.
