this is the simulation output which is showing the air velocities distribution of the proposed jet fans for limiting the smoke spread at an enclosed underground parking (area=11,400 sqm) during a proposed car fire scenario.
the jet fans have two functions, the first is that they are guiding the fresh air from the two northern makeup air shafts to spread across the parking and the second is that they are pushing the smoke towards the exhaust fans shafts and limiting smoke spread at the same time.
from the simulation output we can conclude that the proposed fans will successfully sufficient air flow and air velocities that will limit smoke spread and maintain the required egress conditions for safe egress.
