Abstract:

In this paper smoke control capacity of impulse ventilation system (IVS) was examined in an underground car park with three different fire positions. An analysis is results are related with jet fan thrust, fresh air and exhaust flow rates, size of fire and fire positions. Flow rates of both fresh air and smoke exhaust fans and jet fan placement is indicated before CFD analysis. Fire Dynamic Simulator 6.1.2 is applied to 115 m long, 57 m wide and 3.5 m height domain with simulating car fire whose peak heat release rate (HRR) is 4 MW resulted from burning propane as a fuel in which scoot yield 0.024 kg soot/ kg fuel for three different locations. Velocity, temperature, visibility and CO results obtained by CFD method show that they completely met with indicated standard assumptions.
