In case of fire in atrium shopping mall, the smoke plume flows from the fire compartment opening and rise vertically towards the atrium ceiling. It has been found that as the plume rises vertically, it may curl inward the atrium upper balconies resulting in smoke contamination. Past research found that smoke curling depends upon different parameters which include fire compartment opening width, balcony breadth and depth of plume at spill edge, where 1/10* scale experimental study was performed to investigate the above mentioned parameters without including the effect of down stand. However, research on rising smokeplumes found that the presence of down stand structure at the fire compartment opening would cause the plume to rise closely to the upper balconies, which may cause anincrease in smoke contamination. Down stand is commonly used in shops to display the shop trade name. However,past research did not include the effect of down stand on smoke contarnination in atrium upper balconies.
