Simulation Study on Air Curtain and Smoke Exhaust System of Long Corridor High-rise Building with Regional Ecological Environment Characteristics
Smoke causes visibility to be very low in fires, and the smoke has great harm to personal safety with the toxicity. In addition, the long corridor type building has a flat shape, and the smoke exhaust is longer than the ordinary building exhaust. Therefore, it is easy to cause the personnel to suffer from hypoxia and suffocation. With the extensive application of computer technology, numerical simulation of intelligent calculation of fire smoke in long corridor buildings has become the focus of research. Computers need human-computer interaction, mainstream optimization, computing networks, regions, and scene integration. Combined with the fire smoke movement model, the advantages and disadvantages of each model were analyzed in this paper. An integrated model for intelligent computing was built by using FDS connected with CFAST. Due to the difference of regional ecological environment, there are some differences in outdoor wind speed, temperature and atmospheric pressure in different areas. Therefore, it is necessary to explore the characteristics of regional eco-environmental characteristics (wind speed, temperature and air pressure) on the smoke exhaust system. The results of intelligent calculation can provide reasonable suggestions for the design of smoke exhaust port and smoke exhaust system in long corridor building.
