AB  - In Atria and other large spaces, smoke from fires can flow freely, leading to unusual patterns of smoke
flow. When smoke control systems are designed in Korea, the designer can propose the use of
Performance-Based Design (PBD) methods. In the present study, we perform Computational Fluid Dynamics
(CFD) modeling and Hot Smoke Tests (HSTs) to implement PBD for an atrium. This study introduces an optimal
smoke control system to a target site by comparing the properties of CFD modeling and onsite HSTs in three
design scenarios using a forced air supply/exhaust, natural air supply and natural exhaust via. smoke exhaust
windows. HSTs and a fire dynamics simulator are applied to each scenario and the results are used to identify
variables affecting smoke flow. We distinguish the separate effects of forced ventilation, smoke exhaust window
position and natural air supply on smoke flow. These methods can be used as tools to determine the operating
conditions for smoke control systems, the effects of supply/exhaust vent positioning on smoke control and
building administration measures for Atria of various shapes.
