- Abstract
- Focusing on advancing predictive modelling of upward flame spread using CFD, large eddy simulations using FireFOAM are presented. A fully dynamic approach with respect to turbulence, combustion and radiation, as well as modelling convective heat transfer based on Newton's law with simplified correlations for natural convection, is considered. The thermal decomposition of the solid material is modelled using a 1D pyrolysis model combined with optimised model-effective material properties. For validation purposes, a series of medium-scale Single Burning Item (SBI) experiments using both inert (calcium silicate) and flammable walls (plywood) is considered. Separate validation of the gas (pool fires) and solid (anaerobic pyrolysis) phases is also reported. A comprehensive comparison between the CFD model predictions and available experimental data is performed. The modelling approach performs very satisfactorily with the predictions being rather grid-insensitive and resulting in maximum deviations in the predicted HRR, between the coarsest and finest grid size, on the order of 15%.
