Application of a subgrid soot-radiation model in the numerical simulation of a heptane pool fire

Study of the importance of non-uniform mass density in numerical simulations of fire spread over MDF panels in a corner configuration

“…It is recommended for similar future computational assessments involving flame spread scenarios over MDF panels to consider quantifying the nonuniform panel density effects, as this study shows large implications from the non-uniform mass density on the evolution of key parameters such as HRR, lateral flame spread and char formation. For more elaborate analyses, it is advisable to consider modeling water evaporation and movement inside the wood product [51], explore more sophisticated radiation modeling approaches [52], and evaluate gas phase velocities and temperatures in CFD simulations against experimental data.…”

“…The Finite volume Discrete Ordinates Model (fvDOM) is used to solver for Radiative Transfer Equation (RTE) in FireFOAM, such that the radiation intensity is treated as a function of both spatial location and angular direction, with a total of 48 angles (3 × 4 azimuthal and 4 polar angles), as in [34]. An optically-thin assumption is made and the radiative emission is modeled using a radiant-fraction based approach, where a portion of the chemical HRR is converted to radiation, as expressed below:…”

Non-grey radiative heat transfer modelling in LES-CFD simulated methanol pool fires

“…TRI should be taken into account, as per recommendations from various sources such as [11,12,19,40,41]. As detailed by Snegirev in [41], the expansion of the radiant emission term yields a temperature self correlation and a correlation between the filtered absorption coefficient and temperature.…”

“…It is the banded WSGG that has attracted the most success from the radiation community, which often dismisses grey approximations as inappropriate for inhomogeneous media [8][9][10]. However, reference [10] and more recent CFD works from the fire community [18,19] report satisfactory performance in fires where grey emission by soot particles dominates radiation over non-grey combustion gases (a common approximation for moderately-sooting fires e.g. heptane).…”
