Influence of atrium roof geometries on the numerical predictions of fire tests under natural ventilation conditions

Fire Experiments and Simulations in a Full-scale Atrium Under Transient and Asymmetric Venting Conditions

“…The experiments have been conducted at the fire atrium located in Murcia, Spain ( Figure 1a) [5][6][7][8]23]. This atrium, with dimensions of 19:5 Â 19:5 Â 17:5 m 3 , has four exhaust fans installed at 1.75 m far from the centre, represented in Figure 1b as ''A'', ''B'', ''C'' and ''D''.…”

“…-Wall A. Twelve thermocouples were installed in three thermocouple trees to measure the temperature at 30 cm from the wall A (sensors [14][15][16][17][18][19][20][21][22][23][24][25] as can be observed in Figure 2c. These measurements are used to study the smoke temperature at the far field and the smoke layer drop.…”

“…High-temperature hot smoke will spread quickly from the fire floor to other floors through stairwells [1], glass curtain wall, and elevator shafts by stack effect [2][3][4][5][6]. Ayala et al [5] investigated the influence of different atrium roof geometries on large-scale atrium natural venting conditions and the influence of the atrium aspect ratio on the smoke layer growth by numerical simulations and experimental fire tests. Byström et al [6] conducted a full-scale fire test in a complex enclosure under low ambient temperatures.…”

Review and Validation of the Current Smoke Plume Entrainment Models for Large-Volume Buildings

“…The Fire Atrium characteristics make this the ideal and unique facility for this kind of research. This section provides a summary of [46,66,67]. The burning fuel was heptane contained in circular steel pans placed at the center of the atrium floor.…”
