Merging behavior of facade flames ejected from two windows of an under-ventilated compartment fire

Experimental study on flame merging behaviors from two pool fires along the longitudinal centerline of model tunnel with natural ventilation

“…Lu et al . [16] indicated that the height of merging point affected the air entrainment and the flame height. …”

“…However, most of them [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] were conducted in open space to investigate the effects of fuel type, fire shape, size, number, spacing and array pattern on the mass loss rate (MLR), flame height, flame merging, heat feedback, fire whirl, etc.. For example, Weng et al [2] , Kamikawa et al [3] and Fukuda et al [4] studied the effects of fire spacing and heat release rate (HRR) http …”

Vertical safe separation distance between openings in multi-storey buildings having a fire resistant spandrel

“…The theory and methodology is based on the extensive work done in FireSERT and SKLFS China for enclosure and façade fires [1][2][3][4][5][6]. In reference [6] a review of previous works on façade fires are included.…”

“…The results from [1][2][3][4][5] used in this paper are next summarized for under-ventilated fires: 1. The air inflow for the opening:ṁ…”

“…As the opening dimensions increase more air flows into the compartment leading to the change of conditions from under-ventilated to over-ventilated. This cross over occurs when the total mass pyrolysis rate becomes less than the stoichiometric air requirements [1][2][3][4][5]…”
