CFD Modeling of Full-Size Highrise Fire Smoke Spread and Control (LB-17-C037)

High-rise building fires often lead to disastrous and enormous losses if the fire smoke is not well controlled. This study uses the CFD model, Fire Dynamics Simulator (FDS) developed by the US National Institute of Standards and Technology (NIST), to model the fire smoke spreads and control strategies in a full-size high-rise building. The building is a 302-feet (92 meter) high-rise with two 20-story towers, three-story ground level parking spaces, two stairwells and one elevator shaft. The modeled fire smoke control system is a hybrid venting system with mechanical fan installed at the top of the stairwells. Neutral plane level, smoke temperature and smoke flow inside the building were studied based on the simulation.
