“…The equation predicts the ceiling jet velocity distribution as a function of fire energy release rate, fire-toceiling spacing, distance from the fire plume -ceiling impingement point, and distance below the ceiling. ceiling surfaces [11][12][13]. Also, temperature distributions of ceiling surfaces [14][15][16] and throughout ceiling jets [e.g., [15][16][17][18][19] These upper layer effects have been modeled analytically [11,20,21] and they have been observed experimentally [16,18,22] Figure 4 and used below in the analysis of link response.…”
