An assessment of recent thermal radiation model performance for propane gas fire experiments

“…This finding is supported by Wan et al, 17 who state that the level of precision of the cuboid flame model is far higher than the traditional single-point source model when assessed against propane-based fire experiments. Both Huang et al 16 and Wan et al 17 have demonstrated a reduction in prediction error when applying the cuboid flame model when compared with the single-point source model for propane flame with diameter of 0.17 to 0.34 m; unlike with the single-point source model, the estimated heat flux data evaluated using the cuboid flame model are located within 620% error lines. The conclusions drawn by both Huang et al and Wan et al are at odds with Fleury et al 8 who suggest that the best-performing model on average for propane fire heat flux estimation is the single-point source model.…”

“…Conversely, Huang et al 16 have stated through their research that both the single-point source model and the cuboid flame model are in good agreement with their propane gas fire experimental data. Nevertheless, the cuboid flame model appeared to achieve a slight improvement in terms of predicted percentage error.…”

“…The model was initially targeted specifically for the ignition of everyday household furniture, which are more commonly found as cuboidal shapes rather than cylindrical or spherical. Huang et al 16…”

“…The model was initially targeted specifically for the ignition of everyday household furniture, which are more commonly found as cuboidal shapes rather than cylindrical or spherical. Huang et al 16 have also examined the cuboid flame model, and comparison of heat flux estimation between the cuboid flame model and single-point source model has highlighted the improvement presented by the cuboid flame model. The cuboid flame model assumes that both the top and side surfaces of the cuboid emit radiation with equivalent intensity to the surroundings, as shown by Figure 4.…”

A global model for flame pulsation frequency of buoyancy-controlled rectangular gas fuel fire with different boundaries

“…Poreh and Garrad [24] investigated the flame height of wall and corner fire plumes and proposed two similar correlations to estimate the effect of walls on the mean flame height were developed. Recently, several investigators [19][20][21][25][26][27] studied the influence of sidewalls on the burning behavior of pool fire. Hu et al [28,29] investigated the fire behavior of gas fires constrained by two parallel side walls and wall-attached fire impinging upon an inclined ceiling.…”
