A Study on Wind-Induced Smoke Extraction Systems for Building Fires
Department of Safety, Health and Environmental Engineering, National Kaohsiung First University of Science and Technology, 82445 Kaohsiung City, Taiwan
Since smoke is one of the lethal factors at the scene of a fire, the effectiveness of a smoke control system is of great importance. Buildings are likely to be influenced by natural winds, so the effectiveness of a natural smoke extraction system is often questioned. This study discusses the feasibility of using the Venturi principle to improve a natural smoke extraction system for buildings under the effect of wind. The findings show that side smoke extraction is likely to be influenced by external air flow. Smoke extraction can clearly be improved if a negative pressure zone is formed outside the smoke vent.
