abstract="In order to explore transverse and longitudinal length and flame area distribution features of ceiling jet flow driven by strong plume in a bifurcation tunnel, 5 groups of fire locations (0. 1, 0. 3, 0. 5, 0. 7 and 0. 9 m) and 4 HRR (47. 9, 63. 8, 77. 7 and 95. 7 kW) were selected. Transverse lengths of intermittent flame and transverse continuous flame for typical working conditions were calculated and corresponding critical temperature values were determined, which were 325 and 620 益 respectively. Based on critical values of continuous flame, its transverse and longitudinal flame length as well as flame area were obtained. The results show that there is a non-monotonic trend for transverse flame length as distance from fire source to sidewall increases from 0. 1 m to 0. 7 m, and it will reach maximum value at 0. 3 m. Nevertheless, longitudinal length continuously decreases as distance rises from 0. 1 m to 0. 9 m, and it is always larger than transverse length under same conditions. Flame area increases first with spacing grows from 0. 1 m to 0. 3 m and then decreases as it continuously increases to 0. 7 m. © 2020 China Safety Science Journal<p /><p>Language: zh</p>",
